Answer:
11.41%
Step-by-step explanation:
The cost of equity of an all-equity firm can be derived from the below formula:
Levered Cost of Equity = Unlevered Cost of Equity + (Unlevered Cost of Equity - Cost of Debt) * (1 - tax) * Debt-Equity Ratio
Levered Cost of Equity=13.04%
Unlevered Cost of Equity=the unknown(let us assume it is U)
cost of debt=8%
tax rate=25%
debt-equity ratio=0.64
13.04%=U+(U-8%)*(1-25%)*0.64
13.04%=U+(U-8%)*0.75*0.64
13.04%=U+(U-8%)*0.48
0.1304=U+0.48U-0.0384
0.1304+0.0384=1.48U
1.48U=0.1688
U=0.1688/1.48
U=11.41%
