Answer: 8.38%
Step-by-step explanation:
When calculating Weighted Average Cost of Capital (WACC), use the market values.
WACC:
= (Cost of equity * Proportion of equity) + (After tax cost of debt * Proportion of debt)
If debt is 30% then equity will be 70%.
WACC = (10.60% * 70%) + ( 5.31% * (1 - 40% tax rate) * 30%)
= 7.42% + 0.9558%
= 8.38%
