Answer:
B. Procedural
Explanation:
Remember, the procedural type of justice focuses on identifying the best way to treat others in a fair way, such as following the adhering to the rule of no bias when administering justice.
In this scenario, if the manager decides to select and lay off 10% of his workforce based on their age range, he would be unintentionally displaying an age bias in his selection process, which of course most likely violates the rules of this type of justice.
The cost method of accounting for stock: __________
a. recognizes dividends as income
b. is only appropriate as part of a consolidation
c. requires the investment be increased by the reported net income of the investee
d. requires the investment be decreased by the reported net income of the investee
Answer:
Option a (recognizes.................income) is the correct answer.
Explanation:
The proportion of even more inventories is below 20 percent, therefore the firm sends dividends on the inventories which are incorporated into the personal income tax rate.Dividends paid mostly by the investor, not adjusting as necessary for the investor's total earnings, should be declared as compensation or earnings.The provided situation is not connected with other possibilities. So the above option is the correct answer.
Compute the Work-In-Process transferred to the finished goods warehouse on April 30 using the following information:
Work-In-Process Inventory, April 30 $245
Direct materials purchased during April $220
Work-In-Process inventory, April 1 $270
Direct labor costs incurred $370
Manufacturing overhead costs $320
Direct materials used in production $195
Answer:
$910
Explanation:
Computation for the Work-in-Process transferred to the finished goods warehouse on April 30
Using this formula
Work-in-Process transferred to finished goods warehouse=Work-In-Process Inventory, April 1+(Direct materials used in production+Direct labor costs incurred +Manufacturing overhead costs)-Work-In-Process Inventory, April 30
Let plug in the formula
Work-in-Process transferred to finished goods warehouse=$270 + ($195 + $370 + $320) - $245
Work-in-Process transferred to finished goods warehouse=$270 +$885-$245
Work-in-Process transferred to finished goods warehouse= $910
Therefore the Work-in-Process transferred to the finished goods warehouse on April 30 is $910
Durango Co. has cash receipts of $120,000 and total cash disbursements of $112,000. Durango Co. started with a beginning cash balance of $4,000 and desires an ending cash balance of $8,000. Durango Co. can borrow money in $1,000 increments. How much debt can Durango Co. repay and still meet its desired cash requirement?
Answer:
See below
Explanation:
Form the above, we can compute Durango Co loan repayment as seen below;
= Beginning cash balance + Cash receipts - total cash disbursement
= $4,000 + $120,000 - $112,500 = 11,500
Ending cash balance = $8,000
Then,
= $11,500 - $8,000
= $2,500
It therefore means that Durango Co. can repay $2,500 and still meets its desired cash requirement

a. Indirect Materials
b. Real estate taxes on the factory
c. Salary of production floor manager
d. All of the above would be considered indirect manufacturing costs
Answer:
d
Explanation:

Indirect manufacturing costs are cost of production that cannot be directly linked to a good that is produced.
Examples of indirect manufacturing cost include :
Indirect Materialsutility machine maintenance Real estate taxes on the factoryDepreciation Salary of production floor managerOutput from a process contains 0.02 defective units. Defective units that go undetected into final assemblies cost $25 each to replace. An inspection process, which would detect and remove all defectives, can be established to test these units. However, the inspector, who van test 20 units per hour, is paid $8 per hour, including fringe benefits. Should an inspection station be established to test all units
Answer: Inspection station should be established.
Explanation:
Cost to company if defect is not detected:
= Cost to replace * percentage defects * number of units tested per hour
= 25 * 0.02 * 20 units
= $10 per hour
Inspector is paid $8 per hour.
The fees to the inspector are less than the cost of replacement so the Inspection station should be established as it saves costs.
Fones Inc. and Speed Dial Corp. are two competitors in the mobile phone market. The cost incurred by each company to manufacture smartphones is $200 per unit. Although both the companies sell their smartphones at the same price, Speed Dial Corp. has a larger market share in the smartphone industry. What does this imply
Answer: C. Speed Dial Corp has been able to offer more perceived value than Fones Inc.
Explanation:
Both companies incur the same costs to produce the phone and also sell at the same price. This means that they should be selling the same number of phones in theory. This is not the case however as Speed Dial Corp is selling more.
The reason Speed Dial must be selling more phones is that they sell a better phone for the same price. In offering more value to the customer for the same price, the customers are buying more from Speed Dial than from Fones because they are getting a better deal for the same price which means that Speed Dial's phone is undervalued.
In recent years, rules have tightened such that those who work for the U.S. government in trade negotiations are now restricted from working for lobbyists for foreign firms. Take the stance of either for or against that statement. Provide justification for your stance.
Answer: For this statement.
Explanation:
People will generally offer their loyalties to those who pay them the highest or who pay them at all and companies will typically be loyal to their country of origin.
What this means is that trade negotiators who work for lobbyists of foreign firms will typically want to advance the interests of the foreign firms when negotiating trade deals for the U.S. government.
This presents a problem because the foreign companies might want to negotiate a deal that favors their own countries over the United States so if trade negotiators that are on their side are the ones negotiating for the United States, the U.S. might not get a good enough deal.
Imagine for instance, a person negotiating a trade deal for the U.S. with China but the person works for lobbyists of Huawei. It is reasonable to assume that the person would want to advance the interests of China on behalf of Huawei. Restricting such a person from negotiating for the U.S. reduces such a possibility.

Bloom Company management predicts that it will incur fixed costs of $266,000 and earn pretax income of $360,400 in the next period. Its expected contribution margin ratio is 54%. Required: 1. Compute the amount of total dollar sales. 2. Compute the amount of total variable costs.
Answer:
1. $1,160,000
2. $534,600
Explanation:
1. Computation for the amount of total dollar sales
Using this formula
Total dollar sales=Fixed costs plus pretax income / Contribution margin ratio
Let plug in the formula
Total dollar sales=$626,400 / 54%
Total dollar sales =$1,160,000
($266,000+$360,400=$626,400)
Therefore the amount of total dollar sales is $1,160,000
2.Computation for the amount of total variable costs.
Sales $1,160,000
Less:
Fixed costs ($265,000)
Pretax income ($360,400)
Variable costs $534,600
Therefore the amount of total variable costs is $534,600

Globe Manufacturing Company has just obtained a request for a special order of 12,000 units to be shipped at the end of the current year at a discount price of $7.00 each. The company has a production capacity of 90,000 units per year. At present, Globe is only selling 80,000 units per year through regular channels at a selling price of $11.00 each. Globe's per unit costs at an 80,000 unit level of production and sales are as follows:
Variable manufacturing expenses $4.60
Fixed manufacturing expenses $1.80
Variable selling and administrative expenses $1.00
Fixed selling and administrative expenses $0.45
Variable selling and administrative expense will drop to $0.30 per unit on the special order units. The special order has to be taken in its entirety. This means that by accepting the special order, Globe will be forced to not sell 2,000 units to its regular customers.
Required:
If Globe accepts this special order, by what amount will its net operating income increase or decrease?
Answer:
Globe Manufacturing Company
f Globe accepts this special order, its net operating income will decrease by:
= $19,300.
Explanation:
a) Data and Calculations:
Special order units = 12,000
Special order price = $7.00 each
Annual Production Capacity = 90,000 units
Annual Sales Units = 80,000
Normal selling price = $11
Per unit costs at 80,000 units level:
Variable manufacturing expenses $4.60
Fixed manufacturing expenses $1.80
Variable selling and administrative expenses $1.00
Fixed selling and administrative expenses $0.45
Variable manufacturing expenses $4.60 * 12,000 = $55,200
Fixed manufacturing expenses $1.80 * 10,000 = $18,000
Variable selling and administrative expenses $0.30 * 12,000 = $3,600
Fixed selling and administrative expenses $0.45 * 10,000 = $4,500
Lost revenue from non-sale of 2,000 at $11 = $22,000
Total costs of special order = $103,300
Sales revenue from special order = $84,000 ($7 * 12,000)
The net operating income will decrease by $19,300 ($103,300 - $84,000)

There are linkages between the microeconomic decisions made by managers and the macroeconomic environment. There are numerous examples from the current recession of company layoffs at the micro level, directly influenced by the decline in economic activity at the macro level. For this assignment, research this linkage. How did the recession impact businesses/managers at the macro and micro levels? You may use one company as the basis of your research.
Answer:
One typical example of this linkage between the economy at the macroeconomic level, and business decisions at the macroeconomic and microeconomic level, is what happened with Lehman Brothers in 2008.
Explanation:
Lehman Brothers was one of the main investment banks in the United States. During the years prior to the financial crisis, Lehman Brothers decided to pursue a risky but profitable strategy of over leveraging -lending a lot more money than they had as deposits.
Once the financial crisis hit, a macroeconomic event, it affected the company at the macro and micro level. At the macro level because Lehman Brothers itself ceased to exist as it went bankrupt, and at the micro level, because it had to enter a process to pay off some debtors, and some of the employees who were laid off due to the dissolution of the firm.

Cash dividends were $2. The company did not issue any bonds or repurchase any of its own common stock during the year. The net cash provided by (used in) financing activities for the year was: ___________
Answer:
$57
Explanation:
Repayment of bond = Beginning balance - Ending balance
Repayment of bond = $154 - $89
Repayment of bond = $65 (Outflow)
Increase in common stock = Beginning balance - Ending balance
Increase in common stock = $57 - $47
Increase in common stock = $10 (Inflow)
Dividend paid = $2 (Outflow)
Net cash used in financing activities = Repayment of bond + Dividend paid - Increase in common stock
Net cash used in financing activities = $65 + $2 - $10
Net cash used in financing activities = $57
So, the net cash provided by (used in) financing activities for the year was $57.
The marginal seller is the seller who Group of answer choices cannot compete with the other sellers in the market. would leave the market first if the price were any lower. can produce at the lowest cost. has the largest producer surplus.
Answer:
would leave the market first if the price were any lower.
Explanation:
Utility can be defined as any satisfaction or benefits a customer derives from the use of a product or service.
Thus, any satisfaction or benefits a customer derives from the use of a product or service is generally referred to as a utility.
In Economics, The law of diminishing marginal utility states that as the unit of a good or service consumed by an individual increases, the additional satisfaction he or she derives from consuming additional units would start decreasing or diminishing as the units of good or service consumed increases.
A marginal seller refers to an individual or business firm that is most willing to sell his or her goods and services at a price that is typically equal to their economic cost while forfeiting producer surplus.
A producer surplus is the amount a buyer is willing to pay for a good minus the cost of producing the good.
Hence, a marginal seller is the seller who would leave the market first if the price were any lower.
Assume that Parker Company will receive SF100,000 in 360 days. Assume the following interest rates: U.S. Switzerland 360-day borrowing rate 7% 5% 360-day deposit rate 6% 4% Assume the forward rate of the Swiss franc is $1.0455 and the spot rate of the Swiss franc is $1.0037. If Parker Company uses a Money Market Hedge, it will receive _____in 360 days.
Answer:
$99,414
Explanation:
Calculation to determine how much he will receive If Parker Company uses a Money Market Hedge,
First step is to determine the amount borrowed
Borrowed=(SF100,000/1.05)
Borrowed= SF95,238
Second step is convert SF95,238 to dollar
SF 95,238*$1.0037
=$95,590.38
Now let determine the amount to receive
Amount received=$95,590.38*1.04
Amount received=$99,414
Therefore If Parker Company uses a Money Market Hedge, it will receive $99,414 in 360 days.
a. Develop a probability distribution for x
b. Compute the expected value of x
c. Compute the variance and standard deviation for x
d. Comment on what your results imply about wind conditions during boating accidents
a. Answer:The corresponding probabilities are obtained by converting the percentages into probabilities. That is, by dividing each value with 100.
F/N (where F =percentage of accidents and N =100)
Explanation:
X 0 1 2 3 4
f(X) 0.096 0.57 0.238 0.077 0.019
b. The formula for the expected value of a discrete random variable is E(x)= µ=∑xf(x)
X F(X) X.f(X)
0 0.096 0
1 0.57 0.57
2 0.238 0.476
3 0.077 0.231
4 0.019 0.076
Total 1 1.353
Hence, the value for expected value of X is 1.353
The formula for the variance of the discrete random variables is Var(x)= σ² =∑(x-µ)²f(x)
X F(X) (x-µ) (x-µ)² (x-µ)².f(x)
0 0.096 -1.353 1.8306 0.1757
1 0.57 -0.353 0.1246 0.0710
2 0.238 0.647 0.4186 0.0996
3 0.077 1.647 2.7126 0.2089
4 0.019 2.647 7.0066 0.1331
Total 1 3.235 12.0930 0.6884
Hence, the variance of the random variable x is 0.6884
The formula for the standard deviation of the discrete random variables is
σ=√(∑[(x-µ)².f(x)] )
Thus, the standard deviation is σ= √0.6884
=0.8297
Hence, the standard deviation of the random variable x is 0.8297
When the price of Milk is $5 per gallon consumers demand 1,000 boxes of Boo Berry Cereal. When the price of milk increases to $5.50 per gallon consumers demand 700 boxes of Boo Berry Cereal.
Required:
a. What is the percentage change in the price of milk?
b. What is the percentage change in the quantity demanded for Boo Berry Cereal?
Answer: a. 10%
b. -30%
Explanation:
a. What is the percentage change in the price of milk?
Old price = $5.00
New price = $5.50
Percentage change = ($5.50 - $5.00)/$5.00 × 100
= 0.50/5.00 × 100
= 1/10 × 100
= 10%
Percentage change on price = 10%
b. What is the percentage change in the quantity demanded for Boo Berry Cereal?
Old quantity = 1000
New quantity = 700
Percentage change = (700 - 1000)/1000 × 100
= -300/1000 × 100
= -30%
The percentage change in the quantity demanded for Boo Berry Cereal is -30%.
The Internal Revenue Service (IRS) provides a toll-free help line for taxpayers to call in and get answers to questions as they prepare their tax returns. In recent years, the IRS has been inundated with taxpayer calls and has redesigned its phone service as well as posting answers to frequently asked questions on its website (The Cincinnati Enquirer, January 7, 2010). According to a report by a taxpayer advocate, callers using the new system can expect to wait on hold for an unreasonably long time of minutes before being able to talk to an IRS employee. Suppose you select a sample of callers after the new phone service has been implemented; the sample results show a mean waiting time of minutes before an IRS employee comes on line. Based upon data from past years, you decide it is reasonable to assume that the standard deviation of waiting times is minutes. Use .
a. State the hypotheses. :
b. What is the -value (to 4 decimals)?
c. Using , can you conclude that the actual mean waiting time is significantly less than the claim of minutes made by the taxpayer advocate.

The Internal Revenue Service (IRS) provides a toll-free help line for taxpayers to call in and get answers to questions as they prepare their tax returns. In recent years, the IRS has been inundated with taxpayer calls and has redesigned its phone service as well as posting answers to frequently asked questions on its website (The Cincinnati Enquirer, January 7, 2010). According to a report by a taxpayer advocate, callers using the new system can expect to wait on hold for an unreasonably long time of 14 minutes before being able to talk to an IRS employee. Suppose you select a sample of 50 callers after the new phone service has been implemented; the sample results show a mean waiting time of 12 minutes before an IRS employee comes on line. Based upon data from past years, you decide it is reasonable to assume that the standard deviation of waiting times is 10 minutes. Use a = 0.05.
a. State the hypotheses.
b. What is the p-value (to 4 decimals)?
c. Using a = 0.05, can you conclude that the actual mean waiting time is significantly less than the claim of 14 minutes made by the taxpayer advocate
Answer:
A) Null hypothesis; H0: μ ≥ 14
Alternative hypothesis; Ha: μ < 14
B) P-value ≈ 0.0793
C) The p-value is less than the significance value and thus we will fail to reject the null hypothesis and conclude that the evidence is not sufficient to reject the claim that the actual mean waiting time is significantly less than the claim of 14 minutes made by the taxpayer advocate
Explanation:
We are given;
Population mean time; μ = 14
Sample mean time; x¯ = 12
Population size; n = 50
Standard deviation; σ = 10
A) Let's state the hypotheses;
Null hypothesis; H0: μ ≥ 14
Alternative hypothesis; Ha: μ < 14
B) Let's first find the test statistic from the formula;
z = (x¯ - μ)/(σ/√n)
z = (12 - 14)/(10/√50)
z = -1.41
From online p-value from z-score calculator attached using; z = -1.41: α = 0.05 and one tailed hypothesis, we have;
P-value ≈ 0.0793
C) The p-value is less than the significance value and thus we will fail to reject the null hypothesis and conclude that the evidence is not sufficient to reject the claim that the actual mean waiting time is significantly less than the claim of 14 minutes made by the taxpayer advocate
