Please help, Im having a hard time

An airline charges $150 for an economy class seat, $300 for a business class seat, and $450 for a first class seat. There are two times as many economy class seats as business class seats on an airplane. The revenue from selling all 65 seats on the airplane is $15,000. How many of each type of seat does the airplane have?
