The total number of tickets sold at the Friday night football game was 1,650. Each adult ticket cost $3.50 and each student ticket cost $2.00. The total revenue for ticket sales was $4,650.
Which system of equations could NOT be used to determine the number of adult tickets, a, and
student tickets, s, sold at the game?
Aa + s = 1650
3.5a + 25 = 4650
B 1650 - S= a
3.5a + 25 = 4650
C a + s = 1650
3.5a = 4650 - 25
Da + s = 1650
2a + 3.5s = 4650
