The bigelow company has a cost of equity of 12 percent, a pre-tax cost of debt of 7 percent, and a tax rate of 35 percent.

what is the firm's weighted average cost of capital if the debt-equity ratio is .60?

a. 6.58 percent

b. 9.21 percent

c. 10.01 percent

d. 10.13 percent

e. 11.11 percent

B. 9.21 percent

Explanation:

The formula to compute WACC is shown below:

= Weightage of debt × cost of debt × ( 1- tax rate) + (Weightage of  common stock) × (cost of common stock)

where,  

Weighted of debt = Debt ÷ total firm

The total firm includes debt, and the equity which equals to

= 0.60 + 1 = 1.60

So, Weighted of debt = (0.60 ÷ 1.60) =0.3 75

And, the weighted of common stock = (Common stock ÷ total firm)

                                                              = 1 ÷ 1.60

                                                              = 0.625              

Now put these values to the above formula  

So, the value would equal to

= (0.375 × 7%) × ( 1 - 35%) +  (0.625 × 12%)

= 1.71% + 7.5%

= 9.21%
