Suppose you have $28,000 to invest. You're considering Miller-Moore Equine Enterprises (MMEE), which is currently selling for $40 per share. You notice that a put option with a $40 strike is available with a premium of $2.80. Calculate your percentage return on the put option for the six-month holding period if the stock price declines to $36 per share. (Do not round intermediate calculations. Enter your 6-month return as a percent rounded to 2 decimal places. Omit the "%" sign in your response.)
