Answer:
Step-by-step explanation:
Let c represent the total number of children that attended the show.
Tickets to the show cost 2$ for children and 4$ for adults. Therefore, a total number of c children will pay c × 2 = 2c
Let the amount earned for c children's tickets be represented by y. Therefore, an expression for the total money earned through the sale of c children's tickets will be
y = 2c
