Suppose you buy a round lot of Francesca Industries stock (100 shares) on 65 percent margin when the stock is selling at $15 a share. The broker charges a 8 percent annual interest rate, and commissions are 4 percent of the stock value on the purchase and sale. A year later you receive a $0.75 per share dividend and sell the stock for $21 a share. What is your rate of return on Francesca Industries? Do not round intermediate calculations. Round your answer to two decimal places.
