A school sells child and adult tickets to a play. The school sells a total of 65 tickets and collects a total of $382.50. The price of each child ticket is $4.50, and the price of each adult ticket is $6.50. Which system of
equations can be used to determine the number of child tickets, x, and the number of adult tickets, y, they
sold?

A. 6.50x + 4.50y = 65
x + y = 382.50

B. 4.50x + 6.50y = 65 x + y = 382.50

C. 6.50x + 4.50y = 382.50 x + y = 65

D. 4.50x + 6.50y = 382.50 x + y = 65
