From this result, if the total cost of a student ticket was three-fourths the cost of an adult ticket, and Roberta collected a total of 212.50, what was the total cost of a student ticket?

x=3/4y

20(3/4y)+20y=212.5

Go from there, and when you solve for y, put that back in the original equation at the top for x.
