The school drama club sold 2,400 tickets to a play and made 9,000 dollars from the ticket sales. Student tickets, x, were 3 dollars and adult tickets, y, were 5 dollars. Create a system of two equations to represent this situation, and solve the system.
x+y=2400 y = 2400-x
3x + 5y = 9000
Substitute the blue equation into the second eqution , solve for x then you can solve for y by substituting
this value of x into one of the equations
