Georgia Connections Academy is selling tickets to its Spring Fling. Adult tickets cost $4 and student tickets cost $2.50. The school makes $2,820. Write an equation that represents this situation to find the cost of all adult and student tickets sold. Use the variable s for student tickets and a for adult tickets sold.

Use the above systems of equations to determine how many adult and student tickets were sold.
Adult tickets and
student tickets.
a = 600 - 0.4s
a + s = 900
Substitute the first equation into the second equation:
(600 - 0.4s) + s = 900
Simplify and solve for s:
600 + 0.6s = 900
0.6s = 300
s = 500
Substitute s = 500 into the first equation to solve for a:
a = 600 - 0.4(500)
a = 400
Therefore, 400 adult tickets and 500 student tickets were sold.
a + s = 900
Substitute the first equation into the second equation:
(600 - 0.4s) + s = 900
Simplify and solve for s:
600 + 0.6s = 900
0.6s = 300
s = 500
Substitute s = 500 into the first equation to solve for a:
a = 600 - 0.4(500)
a = 400
Therefore, 400 adult tickets and 500 student tickets were sold.
