Answer: 9.44%
Explanation:
Find the cost of equity using the Gordon Growth model:
Price of stock = Next dividend/ (Cost of equity - growth rate)
68 = (3.54 * 1.07) / (Cost of equity - 7%)
(Cost of equity - 7%) * 68 = 3.79
Cost of equity - 7% = 3.79 / 68
Cost of equity = 3.79 / 68 + 7%
= 12.57%
Cost of debt is the cost using bank loans of 7.2%
Cost of Capital:
= (Weight of debt * Cost of debt * (1 - tax)) + (Weight of equity * cost of equity)
= (40% * 7.2% * ( 1 - 34%)) + (60% * 12.57%)
= 9.44%
