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 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?

  • Algebra 1- PLEASE help - ,

    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 - ,

    what does x stand for and what does y stand for?

  • Algebra 1- PLEASE help - ,

    x=student tickets, y=adult tickets

  • Algebra 1- PLEASE help - ,

    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...
