Two hundred tickets for the school play were sold. Tickets cost $2 for students and $3 for adults. The total amount collected $490. How many student tickets were sold?

  • Algebra - ,

    Solve these two simultaneous equations:
    S + A = 200
    2S + 3A = 490

    Try subtracting
    2S + 2A = 400 from the second equation.
    (I doubled the first equation)

    That will leave you with A = 90 adult tickets sold.

    Now finish the problem.
