The Glee Club sold a total of 60 tickets to their
spring concert. Student tickets (s) cost $5.00 each
and adult tickets (a) cost $8.00 each. If they had
$1,020 in ticket sales, write a system of linear
equations to determine how many adult tickets
they sold.

5 s + 8 a = 1020
s + a = 60
so s = (60-a)
and
5 (60-a) + 8 a = 1020
300 - 5 a + 8 a = 1020
3 a = 720
a = 240
s + a = 60
so s = (60-a)
and
5 (60-a) + 8 a = 1020
300 - 5 a + 8 a = 1020
3 a = 720
a = 240
