Answer:
adult ticket $16
child ticket $12
Explanation:
let x = price of adult tix
y = price of child tix
1) 3x + 4y = $96
2) 2x + 3y = $68
Subtract equation 2 from equation 1 to get:
3) x + y = 28
x = 28 - y (now substitute this into equation 1)
3(28-y) + 4y = 96
84 - 3y + 4y = 96
y = 96 - 84 = 12 (price of child tickets)
Now that you know the value of y, plug it into equation 3:
x + 12 = 28
x = 28 - 12 = 16 (price of adult tickets)
