How much interest would be paid on a credit card at the end of the second 30-day month on a one-year $1,000 loan at a 12.99% annual rate? Assume you pay nothing at the end of the first 30-day month.
a. $109.10
b. $10.92
c. $108.10
d. $10.91
e. $10.80

Answers

The amount of interest that would be paid on a credit card at the end of the second 30-day month is equal to: E. $10.80.

Given the following data:

Principal = $1,000Interest rate = 12.99%Time = 30 days

Conversion:

365 days = 1 year

30 days = X year

Cross-multiplying, we have:

[tex]365X = 30\\\\X=\frac{30}{365}[/tex]

X = 0.08219 year

To determine the amount of interest that would be paid on a credit card at the end of the second 30-day month:

First of all, we would calculate the simple interest for the first 30-day month:

Mathematically, simple interest is given by the formula:

[tex]S.I = \frac{PRT}{100}[/tex]

Where:

S.I is the simple interest.P is the principal amount.R is the interest rate.T is the time measured in years.

Substituting the given parameters into the formula, we have;

[tex]S.I = \frac{1000 \times 12.99 \times 0.08219}{100}\\\\S.I = \frac{1067.648}{100}[/tex]

Simple interest = $10.6765

[tex]S.I = 1000 + 10.6765[/tex]

S.I = $1010.6765.

Now, we can determine the amount of interest that would be paid on a credit card at the end of the second 30-day month:

[tex]S.I_2 = \frac{1010.6765 \times 12.99 \times 0.08219}{100}\\\\S.I_2 = \frac{1079.05}{100}[/tex]

Interest = 10.79$10.80.

D1 = 1.77

   

D2 = 1.77 +0.18

D2 = 1.95

D3 = 1.95 +0.18

D3 = 2.13

PV of remaining dividends in 5 year = D5 x (1+g)/(Ke-g))      

PV of remaining dividends in 5 year = 2.49(1+0.061)/(0.081-0.061)    

PV of remaining dividends in 5 year = $132.0945

Given that g=6.1%, ke=8.1%      

PV of remaining dividends in year = 0 = PV of the remaining dividends in year 5* 1/(1+0.081)^5

= 132.0945 * 1/(1+0.081)^5    

= $89.48624      

As per dividend-discount model, Colgate stock should sell for​ today = PV of Dividends till 5th year + PV of Remaining Dividend at t=0

= $89.48624 + $8.3707    

= $97.8531

= $97.85

Hence, the amount of $97.85 is the price that​ dividend-discount model predict that Colgate stock should sell for​ today.

Helen Bedru is the assistant controller of Cotton Cravat Co., a subsidiary of HG automotive, which manufactures tailpipes, mufflers, and catalytic converters at several plants throughout Ethiopia . Because of pressure for lowerselling prices, Cotton Cravat Co. has had disappointing financial performance in recent years. Indeed, Helen is aware of rumblings from corporate headquarters threatening to close the plant. One of Helen's responsibilities is to present the plant's financial plans for the coming year to the corporate officers and board of directors. In preparing for the presentation, Helen was intrigued to note that the focal point of the budget presentation was a profit-volume graph projecting an increase in profits and a reduction in the break-even point. Curious as to how the improvement would be accomplished, Helen ultimately spoke with Kiruvel Mesfin, the plant manager. Kiruvel indicated that a planned increase in productivity would reduce variable costs and increase the contribution margin ratio. When asked how the productivity increase would be accomplished, Kiruvel made a vague reference to increasing the speed of the assembly line. Helen commented that speeding up the assembly line could lead to labor problems because the speed of the line was set by union contract. Kiruvel responded that he was afraid that if the speedup were opened to negotiation, the union would make a big "stink" that could result in the plant being closed. He indicated that the speedup was the "only way to save the plant, our jobs, and the jobs of all plant employees." Besides, he did not believe employees would notice a 2 or 3 percent increase in speed. Kiruvel concluded the meeting observing, "You need to emphasize the results we will accomplish next year, not the details of how we will accomplish those results. Top management does not want to be bored with details. If we accomplish what we propose in the budget, we will be in for a big bonus."

Required: What advice do you have for Helen Bedru?Support your response with sufficient and sound reasoning​

Answers

Helen Bedru can present the year's budget based on speeding up the assembly line if Kiruvel can further convince her of the possibility of achieving the plant's target. All stakeholders  should be interested in keeping the plant running.

It is the responsibility of Helen to get all the required data for the budget. The budget should be based on verifiable facts and figures without padding. If she is convinced that the plant manager's strategy is implementable, she should work out the budget based on this new strategy.

It makes business sense to allow the plant to lower its variable costs by speeding up the assembly line and eliminating inefficiencies.

Thus, Helen Bedru needs to work with Kiruvel on the details of his strategy to achieve the budget projections.
