Answer:

a. 6.52%

b. 11.06%

Explanation:

For determining the pretax cost of debt, first we have to first find out the after cost of debt which is

As we know that

WACC = Weighted × cost of debt + Weighted × cost of equity

8.3% = (1.15 ÷ 2.15) × cost of debt + (1.15 ÷ 2.15) × 12%

So after solving this the cost of debt is 5.08%

The 2.15 is come from 1 + 1.15

So the pre tax cost of debt is

= 5.08% ÷ (1 - 0.22)

= 6.52%

b. WACC = Weighted × cost of debt + Weighted × cost of equity

8.3% = (1.15 ÷ 2.15) × 0.059+ (1 ÷ 2.15) × cost of equity

After solving this, the cost of equity is 11.06%
