Answer:
The weighted average cost of capital of the firm is 10.125%
Step-by-step explanation:
The computation of the weighted average cost of capital is shown below:
= Cost of equity × weight of equity + cost of debt × (1 - tax rate) × weight of debt
= 15% × $100 ÷ ($100 + $100) + 7% × (1 - 0.25) × $100 ÷ ($100 + $100)
= 15% × 0.5 + 7% × 0.75 × 0.5
= 7.5% + 2.625%
= 10.125%
Hence, the weighted average cost of capital of the firm is 10.125%
We simply applied the above formula
