The Celluloid Cinema sold 150 tickets to a movie. Some of these were child tickets and the rest were adult tickets. A child ticket cost $7.75
and an adult ticket cost $10.25. If the cinema sold $1470 worth
of tickets, which system of equations could be used to determine
how many adult tickets, a, and how many child tickets, c, were sold?
(1) a te - 150
(3) a te - 150
10.25a + 7.750 = 1470 7.75a + 10.250 = 1470
(2) a + 1470
(4) ate 1470
10.25a + 7.750 = 150
7.750 + 10.250 = 150
