Answer:
Firm L's cost of equity is 13.2%
Step-by-step explanation:
In order to calculate Firm L's cost of equity we would have to calculate the following formula:
Firm L's cost of equity=Unlevered cost of equity+D/E*( Unlevered cost of equity-cost of debt)*(1-tax rate)
D/E = debt/equity
D/E = $200,000/$300,000
D/E=0.6666
Therefore, Firm L's cost of equity= 12%+0.6666*(12%-9%)*(1-0.4)
Firm L's cost of equity=13.2%
Firm L's cost of equity is 13.2%
