Answer:
correct option is a. 19.63%
Explanation:
given data
dividend = $3.50 per share
constant rate = 10% per year
common stock = $40 per share
flotation costs = $4 per share
solution
we know formula that is
cost of retained earnings = [tex]\frac{Dividend}{Current price}[/tex] + Growth rate
we will ignored Flotation costs in this case
so it will be = [tex]\frac{3.5 * 1+0.1}{40}[/tex] + 0.1
= 19.63 %
so correct option is a. 19.63%
