Question 591963
The OFY student council voted to go to a baseball game for their annual trip. They bought 30 tickets. Some of the tickets cost $21 each, and some cost $27 each. The total cost of all the tickets was $696. How many of the $21 tickets did they buy?
--------------------------------------------
Hints:

Let's x be the number of $21 tickets and y is the number of $27 tickets.

We will have a linear system of two equations:

Total  bought tickets: x + y = 30

Total cost: 21x + 27y = 696

Solve the system to find x and y.
