An aircraft has 200 seats, and there are two types of fares: full ($499) and discount ($139). During spring break, the airline can sell all its 200 seats at discount for sure but it wants to improve its revenues by allocating some of the seats to full fare customers such as business professionals. Demand for full fares is estimated to have a mean of 50; the table below gives the cumulative distribution function. Assuming that discount customers book before full-fare customers, how many seats should be protected for full-fare customers? (Assume for purposes of this problem that everyone who buys a ticket shows up for the flight.)
