Answer:
8.30%
Step-by-step explanation:
The weighted average cost of capital of the company is computed using the WACC formula below:
WACC=(We*Ke)+(Wp*Kp)+(Wd*kd)
We=weight of common equity=50%
Ke=cost of retained earnings which is a proxy for the cost of equity=11.50%
Wp=weight of preferred stock=20%
Kp=cost of preferred stock=6.00%
Wd=weight of debt=30%
Kd=after-tax cost of debt=4.50%
WACC=(50%*11.50%)+(20%*6.00%)+(30%*4.50%)
WACC=8.30%
