There are 220 tickets to a school's annual awards banquet. Each adult ticket a costs $25 and each student ticket s costs $15. Every ticket is sold and the school makes $4,650. Which system of linear equations could be used to find the number of adult and student tickets sold?

A. a + s = 220

15a + 25s = 4,650

B. a + s = 4,650

15a + 25s = 220

C. a + s = 4,650

25a + 15s = 220

D. a + s = 220

25a + 15s = 4,650
