Answer:
A)8.09%
Step-by-step explanation:
First we have to calculate the Cost of equity of firm using Capital Asset Pricing Model(CAPM).The formula of CAPM is given below:
RE = RF + β (RM – RF)
RE = the cost of equity for a firm’s share.
RF = the risk-free rate of return.
β = the beta factor for the firm’s common stock.
RM – RF=The market risk premium.
Using the above formula Cost of equity of the Firm can be calculated as:
Cost of equity=RE=3%+1.5*9%=16.5%
Debt value of firm=3
Equity value of firm=1
WACC=(Debt value of firm*post tax cost of debt+Equity value of firm*post tax cost of equity)/(Debt value of firm+Equity value of firm)
WACC=(3*8%*66%+1*16.5%)/3+1
= 32.34%/4
=8.09%
so the answer is A)8.09%
