A basketball team sells tickets that cost $10, $20, or, for VIP seats, $30. The team has sold 3061 tickets overall. It has sold 271 more $20 tickets than $10 tickets. The total sales are $58,670. How many tickets of each kind have been sold?
Let x, y and z represents the number of tickets that cost $10, $20, or, for VIP seats, $30 respectively.
Team has sold 3061 tickets overall. Thus,
x + y + z = 3061 ----(1)
Team has sold 271 more $20 tickets than $10 tickets. Thus,
y = 271 + x ----(2)
The total sales are $58,670. So,
10x + 20y + 30z = 58670
=> x + 2y + 3z = 5867 ---(3)
Multiplying both sides of equation (1) by 3, we get
3 * (x + y + z) = 3 * 3061
3x + 3y + 3z = 9183 ----(4)
Subtract (4) from (3), we get
(3x + 3y + 3z) - (x + 2y + 3z) = 9183 - 5867
2x + y = 3316
2x + 271 + x = 3316 (from (2))
3x = 3316 - 271
x = 3045 / 3 = 1015
y = 271 + x = 271 + 1015 = 1286
From (1), x + y + z = 3061
=> 1015 + 1286 + z = 3061
=> z = 3061 - 2301
=> z = 760
So, number of $10, $20, and for VIP seats, $30 sold are 1015, 1286 and 760 respectively.
