7. Suppose a financial manager buys call options on 50,000 barrels of oil with an exercise price of $88 per barrel. She simultaneously sells a put option on 50,000 barrels of oil with the same exercise price of $88 per barrel. Consider her gains and losses if oil prices are $80, $87, $88, $89, and $96. (Do not round intermediate calculations. Leave no cells blank - be certain to enter "0" wherever required. A negative answer should be indicated by a minus sign.)
