Answer: 11.05%
Step-by-step explanation:
The weighted average cost of capital is calculated as follows:
= (Weight of debt * after tax cost of debt) + (weight of equity * cost of equity) + (weight of preferred stock * cost of preferred stock)
Total equity = 28,000 * 71 = $1,988,000
Total preferred stock = 6,900 * 91 = $627,900
Total debt = 380,000 * 107 = $406,600
Total = 1,988,000 + 627,900 + 406,600
= $3,022,500
Cost of preferred stock = Dividend / Current price = 7 / 91 = 7.69%
After tax cost of debt = 7.84% * (1 - 39%) = 4.78%
WACC = (406,000 / 3,022,500 * 4.78%) + (1,988,000 / 3,022,500 * 13.40%) + (627,900 / 3,022,500 * 7.69%)
= 11.05%
