ron and kathy are ticket-sellers at their class play, ron handling student tickets that sell for $3.00 each and kathy selling adult tickets for $6.50 each.
If their total income for 29 tickets was $125.50, how many did ron sell?

    if its elementary algebra don't you draw some columns and guess and test?

    otherwise, these are the equations:

    x(3.00) + y(6.50) = $125.50
    x+y = 29 tickets

  • elementary algebra -

    Let R = # tickets sold by Ron.
    and K = # tickets sold by Kathy.
    =================================
    R+K = 29
    3R + 6.50K = 125.50
    =======================
    Two equations; two unknowns. Solve for R and K.
