Answer:
12.75 %
Explanation:
Cost of Capital is calculated on a Weighted Average basis. This is because there is a Pooling of Funds when it comes to financing projects. So Cost of Capital is the Return that is Required by providers of Long Term source of finance.
Cost of Capital = E/V × Ke + D/V × Kd
Where,
E/V = Market Weight of Equity
= 0.55
Ke = Cost of Equity
= 15%
D/E = Market Weight of Debt
= 0.45
Kd = Cost of Debt
= 10%
Therefore,
Cost of Capital = 0.55 × 15% + 0.45 × 10%
= 12.75 %
