1. Alicia bought eight tickets to a drama at a total cost of $50. She bought student tickets
for $5 each and adult tickets for $7 each. Select the system of equations that can be
solved to find the number of adult tickets, a, and the number of student tickets, s, she
bought.
(a) 5a + 5s = 50 (b) 7a + 5s = 50
a + s = 8 a + s = 8
(c) 5a + 7s = 50 (d) 12as = 50
a + s = 8 a + s = 8
