Answer:
0.143 or 14.3%
Step-by-step explanation:
Tax does not affect the Cost of common stock (Ke) since Dividend is an item of appropriation and not charge against profit.
Annual dividend, D0 = $3.20 per share
Dividends and earnings should grow, g = 9% annually
Selling price of common stock = $66



= 0.053 + 0.09
= 0.143 or 14.3%
