Answer: 8.60%
Step-by-step explanation:
Weighted Average cost of capital = (Cost of equity * Weight of equity) + (After tax cost of debt * Weight of debt)
Weight of debt = Debt-equity ratio / (1 + Debt-equity ratio)
= 73% / (1 + 73%)
= 42.1965%
Weight of Equity = 1 / (1 + Debt - equity ratio)
= 1 / 1.73
= 57.8035%
WACC = (11.3% * 57.8035%) + (4.9% * 42.1965%)
= 8.60%
