RamsayRamsay Travel offers helicopter service from suburban towns to John F. Kennedy International Airport in New York City. Each of its 12 helicopters makes between 900 and 1,500 round-trips per year. The records indicate that a helicopter that has made 900round-trips in the year incurs an average operating cost of $750 per round-trip, and one that has made 1,500 round-trips in the year incurs an average operating cost of $600 per round-trip. 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 RamsayRamsay Travel expects each helicopter to make, onaverage, 1,200
round-trips in the coming year, what should its estimated operating budget for the helicopter fleet be?
