A concert hall earned $40,000 in sold−out comedy ticket sales. Front section tickets cost $150 per seat and back section tickets cost $50 per seat. The number of front section seats is three times the number of back section seats. How many seats are in the front section?

Question

anonymous · Answer

Create a system of equations for it and solve them simultaneously.

Let 'f' be the number of front-row seats, and 'b' the number of back-row seats:

150f + 50b = 40,000
f = 3b
