Suppose a financial manager buys call options on 22,000 barrels of oil with an exercise price of $72 per barrel. She simultaneously sells a put option on 22,000 barrels of oil with the same exercise price of $72 per barrel. What are her payoffs per barrel if oil prices are $64, $67, $72, $77, and $80? (Leave no cells blank - be certain to enter "0" wherever required. A negative answer should be indicated by a minus sign.)
