this is clearly an algebra problem.  It's necessary that you choose a letter (such as x) to represent the number of child tickets sold and another letter (such as y) to represent the number of adult tickets sold.  You are told the price of each of the 2 types of tickets.
Write an equation for the income from ticket sales in terms of these prices and the variables x and y.

The problem asks you to let c=number of child tickets sold, and a=number of adult tickets sold.  Whichever variables you choose to use, the results will be and must be exactly the same.
