c + a = 250 - - - - - - - - - - 1

The cost for a child's ticket is $12.75, while an adult ticket costs $18.50. The total ticket sales amounting to $4739.50 indicates that:

12.75c + 18.5a = 4739.50 - - - - - - - 2

Equations 1 and 2 form the system necessary to find the number of adult tickets, a, and child tickets, c, sold.
