Math Problem Statement
The hourly operating cost of a certain plane, which seats up to 150 passengers, is estimated to be $7,810. If an airline charges each passenger a fare of $220 per hour of flight, find the hourly profit P it earns operating the plane as a function of the number of passengers x. [HINT: The cost function is constant (variable cost = 0).]
P(x) =
