Answer:
Cost of equity is 11.2%
WACC is 8.74%
Explanation:
The formula for cost of equity is given below:
Cost of equity=risk free rate+(Beta *risk premium)
risk free rate is the treasury bill rate of 4%
Beta is 0.9
market risk premium is 8%
cost of equity=4%+(0.9*8%)=11.2%
WACC=Ke*E/V+Kd*D/V*(1-t)
Ke is the cost of equity of 11.2%
Kd is the cost of debt of 5%
t is the tax rate of 40% or 0.4
E is the equity weighting of 70% or 0.7
D is the debt weighting of 30% or 0.3
V is the E+D=0.7+0.3=1
WACC=11.20%
*0.7/1+(5%*0.3/1*(1-0.4)
WACC=7.84%
+0.90%
=8.74%
