You must first make an equation based on the information provided in the question.

It is stated that the $15,000 in revenue came from selling 65 seat. Of these 65 seat, we know there were 2 times as many economy passengers as there are business passengers. So let's make some variables. If we name business passengers "x" then that means economy passengers must be "2x" the total of the economy and business passengers is 3x, meaning the amount of first class passengers would be "65-3x"

Lets write the equation:

150(2x) + 300x + 450(65-3x) = 15000

Solve for x, you will get x=19

economy is 2x which equals 38 passengers

business is x which equals 19 passengers

first class is 65-3x which equals 8 passengers
