Answer:
a. 8.79%
Explanation:
WACC = Weight of debt * Pretax cost * (1 - Tax) + Weight of Equity * Cost of Equity
Value of Equity = 10,700 * $63 = $674,100
Value of debt = 320 * $1000 * 93.6% = $299,520
Weight of Debt = $299,520/($299,520 + $674,000) = 30.76%
Weight of Equity = $674,000/($299,520 + $674,000) = 69.24%
WACC = 30.76% * 5.89% * (1 - 40%) + 69.24% * 11.13%
WACC = 30.76% * 5.89% * 0.60 + 69.24% * 11.13%
WACC = 0.010870584 + 0.07706412
WACC = 0.087934704
WACC = 8.79%
