Which system of equations can be used to solve the following problem?
Each child ticket for a ride costs $3, while each adult ticket costs $5. If the ride collected a total of $115, and 33 tickets were sold, how many of each type of ticket were sold? Let c be the number of child tickets and a be the number of adult tickets.
the answer is C. 5c+3a=115 c + a=33 if each child's ticket is $3 and there are 4 child tickets sold, then the total is 3×4
if each child ticket is $3 and there are "c" child tickets sold, the total is 3c for the childs tickets
