You can put this solution on YOUR website!
Let x = orchestra seats
Let y = balcony seats
We have a system of linear equations in two variables.
Here is the set up and you can then work out the math:
x + y = 650
20x + 12y = 11,600

A theater has 650 seats. After one sell-out performance, the theater made $11,600. If orchestra seats cost $20 each and balcony seats cost $12, how many orchestra and balcony seats are there in the theater?

let orchestra seats be x
AND balcony seats y
20x+12(650-x)= 11600
20x+7800-12x=11600
8x=11600-7800
8x=3800
x=475 - orchestra seats
Balance 175 will be balcony seats
