You can put this solution on YOUR website! Hi there,
I take it you mean adult's tickets cost $8 and kid's tickets cost $5.
Make adult's tickets = x
Make kid's tickets = y
x + y = 28.......Eq(1)
8x + 5y = 164....Eq(2)
Multiply Eq(1) by 8
8x + 8y = 224....Eq(1)
8x + 5y = 164....Eq(2)
Subtract Eq(2) from Eq(1)
3y = 60
y = 20.
Substitute y = 20 into Eq(1)
x + y = 28.....Eq(1)
x + 20 = 28
x = 28 - 20
x = 8
8 Adult's tickets and 20 kid's tickets were sold.
Hope this helps :-)
