Roberta sold fifty tickets for the school play. Roberta sold ten more student tickets than adult tickets. How many student tickets did Roberta sell?
From this result, if the total cost of a student ticket was threefourths the cost of an adult ticket, and Roberta collected a total of 212.50, what was the total cost of a student ticket?

Algebra 1 PLEASE help 
Jen,
30x+20y=212.50
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. 
Algebra 1 PLEASE help 
123ABC,
what does x stand for and what does y stand for?

Algebra 1 PLEASE help 
Jen,
x=student tickets, y=adult tickets

okay.. but...20(3/4y)+20y=212.5 ... when u solve this we get a decimal... and is this equation to find the COST of a student ticket...
