Answer:
WACC is 9.26%
Step-by-step explanation:
WACC is the average cost of capital of the firm based on the weightage of the debt and weightage of the equity multiplied to their respective costs.
According to WACC formula
WACC = ( Cost of common share x Weightage of common share ) + ( Cost of Preferred share x Weightage of Preferred share ) + ( Cost of debt x Weightage of debt )
Cost of debt is already given as after tax cost of debt.
WACC = ( 12.75% x 45% ) + ( 7.5% x 15% ) + ( 6% x 40% )
WACC = 5.7375% + 1.125% + 2.4% = 9.2625 % = 9.26%
