Finn bought 12 movie tickets. student tickets cost $4, and adult tickets cost $8. finn spent a total of $60. write and graph a system of equations to find the number of student and adult tickets finn bought.

S will stand for the number of studen tickets while A will be for adult tickets.
The first equation will be for how many tickets there are 
S+A=12
The second will be the cost.
4S+8A=60
We will multiply the first equation by -4 to eliminate S.
-4S-4A=-48
4S+8A=60
4A=12
12÷4=3
So he bought 3 adult tickets, meaning the remaining tickets had to be students.
So, he bought 3 adult tickets and 9 student tickets.
