The school that Jenna attends is selling tickets to a choral performance. On the first day of ticket sales the school sold 3 senior citizen tickets and 1 child ticket for a total of $38. The school took in $52 on the second day by selling 3 senior citizen tickets and 2 child tickets. What is the cost of a child ticket and the cost of a senior citizen ticket? Which equations represent the system that could be used? Let ( c ) represent the cost of a child ticket. Let ( s ) represent the cost of a senior citizen ticket.

• ( 1c + 3s = 38 ) ( 2s + 3c = 52 )

• ( 3s + 1c = 38 ) ( 3s + 2c = 52 )

• ( s + c = 38 ) ( 8 + c = 52 )

• ( 3s + 3c = 38 ) ( 1s + 2c = 52 )
