X = y + 5
-y + x - x = y - y + x + 5
-y = x + 5
y = x - 5
If we let x and y represent the prices of adult and child tickets, respectively, then we can write two equations based on the daily sales.
8x +5y = 108
x +14y = 67
A graphing calculator shows the solution of these equations to be
(x, y) = (11, 4)
The price of an adult ticket is $11.
The price of a child ticket is $4.
6x > 4x+26+8
2x > 34<span>
so,
x > 17 </span>
