Suppose you buy a round lot of Francesca Industries stock (100 shares) on 50 percent margin when the stock is selling at $30 a share. The broker charges a 9 percent annual interest rate, and commissions are 3 percent of the stock value on the purchase and sale. A year later you receive a $0.80 per share dividend and seil the stock for $38 a share. What is your rate of return on Francesca Industries? Do not round intermediate calculations. Round your answer to two decimal places
