Roche Travel offers helicopter service from suburban towns to John F. Kennedy International Airport in New York City. Each of its 14 helicopters makes between 1,200 and 2,400 round-trips per year. The records indicate that a helicopter that has made 1,200 round-trips in the year incurs an average operating cost of $535 per round-trip, and one that has made 2,400 round-trips in the year incurs an average operating cost of $500 per round-trip. i Requirements y is the total annual operating cost of a helicopter and X is the number of round-trips it makes to JFK airport during the year. 1. Using the high-low method, estimate the linear relationship y = a +bX, where y is the total annual operating cost of a helicopter and X is the number of round-trips it makes to JFK airport during the year. 2. Give examples of costs that would be included in a and in b. 3. If Roche Travel expects each helicopter to make, on average, 1,800 round-trips in the coming year, what should its estimated operating budget for the helicopter fleet be? Print Done
