a.
WACC is calculated as –
WACC = (Weight of common stock X Cost of common stock) + (Weight of preferred stock X Cost of preferred stock) + (Weight of debt X After tax cost of debt)
WACC = (64% X 13.4%) + (9% X 6.4%) + (27% X ((1- 40%)*8.1%))
WACC = 10.46%
b. After tax cost of debt is calculated as –
After tax cost of debt = (1- tax rate) X cost of debt pre-tax
After tax cost of debt = ((1- 40%)*8.1%))
After tax cost of debt = 4.86%
Answer:
![A = 28000 [\frac{0.12 (1.12)^4}{(1.12)^4 -1}]](https://tex.z-dn.net/?f=%20A%20%3D%2028000%20%5B%5Cfrac%7B0.12%20%281.12%29%5E4%7D%7B%281.12%29%5E4%20-1%7D%5D)
![A = 28000 [\frac{0.12*1.574}{1.574-1}]](https://tex.z-dn.net/?f=%20A%20%3D%2028000%20%5B%5Cfrac%7B0.12%2A1.574%7D%7B1.574-1%7D%5D)

So then the annual pay would be $ 9218.564 for this case
Explanation:
For this question we can use the Equivalent annual value (A) given by the following expression:
![A = PV [\frac{i (1+i)^t}{(1+i)^t -1}]](https://tex.z-dn.net/?f=%20A%20%3D%20PV%20%5B%5Cfrac%7Bi%20%281%2Bi%29%5Et%7D%7B%281%2Bi%29%5Et%20-1%7D%5D)
Where
represent the pesent value
since the rate is yearly
since we have 4 years to pay
So then we have everything to replace and we got:
![A = 28000 [\frac{0.12 (1.12)^4}{(1.12)^4 -1}]](https://tex.z-dn.net/?f=%20A%20%3D%2028000%20%5B%5Cfrac%7B0.12%20%281.12%29%5E4%7D%7B%281.12%29%5E4%20-1%7D%5D)
![A = 28000 [\frac{0.12*1.574}{1.574-1}]](https://tex.z-dn.net/?f=%20A%20%3D%2028000%20%5B%5Cfrac%7B0.12%2A1.574%7D%7B1.574-1%7D%5D)

So then the annual pay would be $ 9218.564 for this case
And this amount would be paid each year in order to pay all the money after 4 years.
Answer: are incurred even if nothing is produced.
Explanation:
Fixed costs are referred to as the cost that doesn't vary with the production level. Even if the company doesn't produce anything, the fixed cost will still be incurred.
The fixed cost is different from the variable cost which is the cost that varies along with production. Examples of fixed cost include salaries, rental lease payments, salaries, etc.
