The Bulldog Theater charges $9.10 for adult tickets and $7.75 for student tickets. Mrs. Williams purchased 7 tickets (some students and some adult) for $56.95. Which system of equations could be used to find a, the number of adult tickets, and s, the number of students tickets Mrs. Williams purchased?

9.10a + 7.75 = 56.95

a + s = 7 9.10a + 7.75s = 56.95

a + s = 56.95 7.75a + 9.10s = 7

7.75a + 9.10s = 56.95 a + s = 7
