Answer:
The WACC is 6.75%
Explanation:
The weighted average cost of capital, also called WACC, is the cost of a firm's capital structure. The capital structure is made up of debt, preferred stock and common stock.
The formula for WACC is,
WACC = wD * rD * (1 - tax rate) + wP * rP + wE * rE
Where,
The WACC is:
WACC = 0.75 * 0.08 * (1 - 0.35) + 0.05 * 0.09 + 0.20 * 0.12
WACC = 0.0675 or 6.75%
