Answer:
A .Unlevered cost of equity = 9.6
b-1 Levered cost of equity = 28.69
b-2 Levered cost of equity = 14.37
b-3 Levered cost of equity = 9.6
Explanation:
A. First step is to calculate the E/A
D/A = D/(E+D)
D/A = 1.5/(1+1.5)
D/A=0.6
E/A = 1-D/A
E/A=1-0.6
E/A=0.4
Second Step is to calculate WACC using this formula
WACC = Levered cost of equity*E/A+Cost of debt*(1-tax rate)*D/A
Let plug in the formula
0.096= Levered cost of equity*=0.4+0.057*(1-0)*=0.6
Levered cost of equity =15.45%
Third step is to calculate UnLevered cost of equity using this formula
Levered cost of equity = Unlevered cost of equity+D/E*( Unlevered cost of equity-cost of debt)*(1-tax rate)
Let plug in the formula
0.1545 = Unlevered cost of equity+1.5*(Unlevered cost of equity-0.057)*(1-0)
Unlevered cost of equity = 9.6
b-1. Calculation for What would the cost of equity be if the debt-equity ratio were 2.0
Using this formula
Levered cost of equity = Unlevered cost of equity+D/E*( Unlevered cost of equity-cost of debt)*(1-tax rate)
Let plug in the formula
Levered cost of equity = 9.6+2*(9.6-0.057)*(1-0)
Levered cost of equity = 28.69
b-2. Calculation for What would the cost of equity be if the debt-equity ratio were 0.5
Using this formula
Levered cost of equity = Unlevered cost of equity+D/E*( Unlevered cost of equity-cost of debt)*(1-tax rate)
Let plug in the formula
Levered cost of equity = 9.6+0.5*(9.6-0.057)*(1-0)
Levered cost of equity = 14.37
b-3. Calculation for What would the cost of equity be if the debt-equity ratio were zero
Using this formula
Levered cost of equity = Unlevered cost of equity+D/E*( Unlevered cost of equity-cost of debt)*(1-tax rate)
Let plug in the formula
Levered cost of equity = 9.6+0*(9.6-0.057)*(1-0)
Levered cost of equity = 9.6
