Answer:
0.147 or 14.7%
Explanation:
Equity (E) =$7
Debt (D) = $1
Cost of equity capital (Ce) = 0.16
Pretax cost of debt (Cd) = 0.08
Tax rate (r) = 0.3
The weighted average cost of capital of the firm is given by the following relationship:
[tex]WACC=\frac{E}{E+D}*C_e +\frac{D}{E+D}*C_d*(1-r)\\WACC = \frac{7}{7+1}*0.16 +\frac{1}{7+1}*0.08*(1-0.3)\\WACC= 0.14+0.007\\WACC =0.147 = 14.7\%[/tex]
The weighted average cost of capital of the firm is 0.147 or 14.7%.
