Answer:
9.55%
Step-by-step explanation:
WACC for the project=We*Ke+Wp*Kp+Wd*Kd*(1-tax rate)
We=weight of equity=equity value/total cost of the project=$880,000/$1,708,000=51.52%
Wp=weight of preferred stock=preferred stock value/total cost of the project=$78,000/$1,708,000=4.57%
Wd=weight of debt=value of debt/total cost of the project=$750,000/$1,708,000=43.91%
Ke=cost of equity=13.2%
Kp=cost of preferred stock=9.9%
Kd=cost of debt=8.7%
tax rate=40%
WACC for the project=(51.52% *13.2%)+(4.57% *9.9%)+(43.91% *8.7%)*(1-40%)=9.55%
