You are selling tickets for a high school basketball game. Student tickets cost $3 and general admission tickets cost $5. You sell 350 tickets and collect 1450. How many of each type of ticket did you sell?
2 Answers
150 at $3 and 200 at $5
Explanation:
We sold some number,x, of $5 tickets and some number,y, of $3 tickets. If we sold 350 tickets total then x + y = 350. If we made $1450 total on ticket sales, then the sum of y tickets at $3 plus x tickets at $5 needs to equal $1450.
So,
$3y + $5x = $1450
and x + y = 350
Solve system of equations.
3(350-x) + 5x = 1450
1050 -3x + 5x = 1450
2x = 400 -> x=200
y + 200 = 350 -> y=150
