Devon purchased tickets to an air show for 9 adults and 2 children.
The total cost was $252. The cost of a child's ticket was $6 less than the cost of an adult's ticket. Find the price of an adult's ticket and a child's ticket.
-----------------------------
Equations:
c = a - 6
9a + 2c = 252
------------------------
Substitute and solve for "c":
9a + 2(a-6) = 252
9a + 2a - 12 = 252
11a = 264
a = $24 (price of adult ticket)
c = a-6 = $18 (price of child ticket)
