Answer:
The price of adult tickets = $27
The price of child tickets = $16
Step-by-step explanation:
The price of adult tickets = x
The price of child tickets = y
4x +3y = 156 ---------------------> equ 1
3x + 4y = 145 ---------------------> equ 2
multiply equ 1 by 3 ===> 12x + 9y = 468
multiply equ 1 by 4 ===> <u>12x + 16y = 580</u>
subtract , -7y = -112
y = -112/-7
y = 16
Substitute y value in equ 1,
4x + 3*16 = 156
4x + 48 = 156
4x = 156 - 48
4x = 108
x = 108/4
x = 27
The price of adult tickets = $27
The price of child tickets = $16
