Answer: 12.5%
Explanation:
Amount that will be raised with Equity = 65% * 5,700,000 = $3,705,000
This is more than the retained earnings so new equity will have to be issued at cost of 16%
Amount raised by debt = 35% * 5,700,000 = $1,995,000
Less than $2 million so cost of debt is 10%
WACC = cost of equity * weight of equity + weight of debt * cost of debt * ( 1 - tax rate)
= (16% * 65% ) + (35% * 10% * (1 - 40% tax))
= 12.5%
