Suppose you believe that Apple's stock price is going to increase from its current level of $ 61.80 sometime during the next 5 months. For $ 479.66 you could buy a 5-month call option giving you the right to buy 100 shares at a price of $ 76 per share. If you bought a 100-share contract for $ 479.66 and Apple's stock price actually changed to $ 89.98 at the end of 5 months, and after behaving economically rationally on your decision to exercise the option, your net profit (or loss) would be ______? Show your answer to the nearest .01. Do not use $ or + sign in your answer. However, use a - sign if you lose money on the contract
