Answers

Answer: A) meeting a customer's expectations doesn't always lead to brand loyalty.

Explanation:

It is possible to meet the expectations of a supplier and the supplier would still move on if they feel like they would get a better deal somewhere especially if the other supplier meets their expectations even better than the first supplier did.

The company in question preferred that it received its parts all at once and the supplier could not do that but they were still able to supply the goods required. They were therefore meeting expectations but not in an adequate enough manner which is why the company found someone better.

The 1974-1975 recession was a result of a: ANSWER Unselected supply shock that caused a leftward shift of the short-run aggregate supply curve Unselected housing bubble collapse that caused a leftward shift of the aggregate demand curve Unselected supply shock that caused a leftward shift of the long-run aggregate supply curve Unselected I DON'T KNOW YET

Answers

Answer: supply shock that caused a leftward shift of the short-run aggregate supply curve

Explanation:

One of the main causes of the 1974 - 1975 recessions was the raising of oil prices and then the subsequent oil embargo on the United States by Arab members of the Organization of the Petroleum Exporting Countries(OPEC).

OPEC did not like the support that the United States was giving Israel and so placed an embargo on the U.S. such that the U.S. could no longer get much oil from the Middle East which she heavily relied upon.

This reduced the supply of oil drastically to the U.S. and resulted in a supply shock that shifted the short run aggregate supply curve to the left to reflect the fuel scarcity and the effect it had on the economy as production slowed down.

Answer: Customer retention

Explanation:

A debtor owed a creditor $1,200 on a promissory note that was due on August 1. After the debtor told the creditor that he might not be able to pay the note on its due date, the creditor agreed to extinguish the debt if the debtor, who was the manager of a discount electronics store, bought a new entertainment system that sold for $1,200 and had it delivered to the creditor's home by August 15. Because the debtor would have to pay only $600 for the system due to his manager's discount, he agreed and the parties signed a written contract on July 26. Is the new agreement between the debtor and the creditor legally enforceable

Answers

Answer:

The correct option is C. Yes, because the debtor incurred a different obligation than he already had.

Explanation:

Note: This question is not complete as the options are omitted. The question is therefore completed before answering the question by providing the options as follows:

A. No, because the debtor incurred no additional detriment that would serve as consideration for the new agreement.

B. Yes, because it would have cost the creditor $1,200 to purchase the entertainment system himself.

C. Yes, because the debtor incurred a different obligation than he already had.

D. Yes, because the new agreement between the debtor and the creditor is enforceable with or without

Explanation of the answer is now provided as follows.

It is possible to enforce the two parties' new agreement as an accord.

An accord can be described as an agreement in which one party to an existing contract agrees to accept some other, different performance from the other party in lieu of the performance that the other party is obligated to provide. In principle, an agreement must be backed by payment, but the consideration can be less than the amount agreed upon in the preceding contract if it is of a different character or the claim is to be paid to a third party. The responsibility of the debtor to supply the creditor with a new entertainment system was enough fresh consideration to constitute a legal agreement in this case.

When a party's responsibility is modified in some way, as the debtor's duty was in this case, the preceding legal duty rule does not apply. It makes no difference whether the creditor's benefit in the accord arrangement is equal to the original debt's worth; courts will find appropriate consideration if the consideration is fresh or different in any way. The difference in the debtor's obligation, that is, payment is in the form of an entertainment system rather than cash) is enough to sustain the accord arrangement, regardless of how much the entertainment system would have cost the creditor.

The Uniform Commercial Code (UCC) does not apply because the original agreement was not for the sale of goods. The underlying commitment in this case was to pay a debt secured by a promissory note.

Therefore, the correct option is C. Yes, because the debtor incurred a different obligation than he already had.

A manufacturer of disposable foam products entered into a written contract with a take-out restaurant to sell them 5,000 disposable foam food containers per month at 5 cents per food container for a two-year period. Per the contract, payment of $250 was due once a month. The restaurant was also responsible for paying shipping charges, which were payable on a quarterly basis. Finally, the contract stated that if any of the containers were discovered to be damaged, they could be returned for a full refund. However, the contract was silent with regard to the return of any containers that were not damaged. In the last month of its contract with the manufacturer, the restaurant decided to switch to biodegradable, recycled cardboard food containers because its take-out customers complained about the harmful effects of disposable foam products on the environment. The restaurant asked the manufacturer not to ship the final shipment, but the manufacturer refused. The restaurant had not yet made the $250 payment for the final shipment of containers, but it did owe the manufacturer delivery charges for its final quarter. The restaurant returned all of the containers to the manufacturer. In addition, the restaurant sent an envelope with cash for the final shipping charges. In the envelope, the restaurant included a brief memo stating that the cash included was for payment in full, including all food containers and shipping charges. The manufacturer's accounting department received the envelope, read the memo, and deposited the cash. The manufacturer then sued the restaurant for the final payment of $250. Which of the following legal concepts would be the strongest argument against payment of $250?
A. Novation
B. Good-faith modification
C. Estoppel
D. Accord and satisfaction

Answers

Answer:

Option B

Explanation:

Since the contract did not mentioned any thing about the retuning of containers that were not defective, it becomes the obligation of the buyer to pay the final delivery amount on the basis of Good-faith modification.

A restaurant has an average check of $15, with an average variable cost of $6. Fixed costs are $150000. What is breakeven sale revenue?

Answers

Answer:

Break-even point (dollars)= $250,000

Explanation:

Giving the following information:

Selling price= $15

Unitary variable cost= $6

Fixed cost= $150,000

To calculate the break-even point in sales dollars, we need to use the following formula:

Break-even point (dollars)= fixed costs/ contribution margin ratio

Contribution margin ratio= unitary CM / Selling price

Contribution margin ratio= (15 - 6) / 15

Contribution margin ratio= 0.6

Break-even point (dollars)= 150,000 / 0.6

Break-even point (dollars)= $250,000

At a recent meeting, your salespeople report that the introduction of competing products has reduced the expected sales of your new product to $3 million.

Answers

Answer:

Yes; $2.0 million

Explanation:

Yes, YOU SHOULD GO AHEAD and do so reason been that the TOTAL LOSS would then be the amount of $3 million calculated as [( -$5million)+(-$1 million)+$3 million=-$3 million] instead of the amount of $5 million which therefore means that The MOST YOU SHOULD PAY in order to complete the development would be the amount of $2 million calculated as ($5 Million-$3 Million).

A bank agreed to lend a merchant $10,000 for one year at 8% interest. The loan proceeds were to be disbursed within two weeks. The merchant intended to use the loan proceeds to purchase a specific shipment of carpets for resale at an expected profit of $5,000 but said nothing about these plans to the bank. The bank failed to disburse the proceeds and refused to assure the merchant that it would do so. The merchant was able to secure a loan from another lender at 10% interest for one year. However, by the time the merchant started the application process for a substitute loan, it was too late to pursue the opportunity to buy the shipment of carpets. In an action against the bank for breach of contract, which of the following amounts is the merchant likely to recover?
Answers:
A. Nothing, because damages lost opportunities are not recoverable.
B. Nothing, because the parties failed to tacitly agree that the merchant would be entitled to damages in the event of a breach by the bank.
C. The difference in cost over time between a loan at 10% and a loan at 8%.
D. $5,000, the merchant's foreseeable loss.

Answers

Answer: C. The difference in cost over time between a loan at 10% and a loan at 8%.

Explanation:

The first bank cannot be held liable for damages relating to the loss of the opportunity to buy the carpets because they were not informed of it and so could not have made a decision based on it.

Another thing they cannot be held liable for is the merchant's inability to get another loan in time because it is assumed that there are other banks that the merchant could have gone to. What they can be held liable for however, is the difference in the types of loans.

The merchant had to get a loan with a higher interest rate because they couldn't honor their agreement so they will pay the difference in interest between their loan and the one the merchant was able to get.

Zumwalt Corporation's Class S bonds have a 12-year maturity, $1,000 par value, and a 5.75% coupon paid semiannually (2.875% each 6 months), and those bonds sell at their par value. Zumwalt's Class A bonds have the same risk, maturity, and par value, but the A bonds pay a 5.75% annual coupon. Neither bond is callable. At what price should the annual payment bond sell? (hint: Bonds with same risk should have same effective rate of return, or YTM).

Answers

Answer:

$993.23  

Explanation:

Note that the yield to maturity for the Class S bond is 5.75% because when a bond sells at par its coupon rate and yield should be the same.

However, Class A, pays annual coupons and the fact they both have the same level of risk means that yields are the same, however, S's yield is 5.75% compounded semiannually, in the case of A we need  an equivalent yield but compounded once a year since annual coupons are to be made, as a result, for A we would convert the yield to an equivalent effective annual yield

EAR=(1+yield/2)^2-1

there are 2 semiannual periods in a year, that is the reason for 2 in the formula above

EAR=(1+5.75%/2)^2-1

EAR=5.83%

The price of bond A is the present value of 12 annual coupons and face value discounted at 5.83% effective annual yield

annual coupon= 5.75%*$1,000

annual coupon=$57.50

bond price=$57.50/(1+5.83%)^1+$57.50/(1+5.83%)^2+$57.50/(1+5.83%)^3+$57.50/(1+5.83%)^4+$57.50/(1+5.83%)^5+$57.50/(1+5.83%)^6+$57.50/(1+5.83%)^7+$57.50/(1+5.83%)^8+$57.50/(1+5.83%)^9+$57.50/(1+5.83%)^10+$57.50/(1+5.83%)^11+($1000+$57.50)/(1+5.83%)^12
