Michelle sold tickets for the basketball game. Each adult ticket costs 3$ and each student ticket costs 1.50. There were 105 tickets sold for a total of 250$. How many of each type of ticket were sold?

  • Algebra -

    x = adult tkts
    y = student tkts
    3x = value of adult tkts
    1.5y = value of student tkts

    x + y = 105
    3x + 1.5y = 250

    solve these equation together
    for your answer

    How do you solve the equations? ):

  • Algebra -

    (1) x + y = 105
    (2) 3x + 1.5y = 250

    multiply equation (1) by -3
    -3 (x + y = 105) = -3x - 3y = -315

    add the two equations together
    -3x - 3y = -315
    3x + 1.5y = 250
    0 - 1.5y = - 65
    -1.5y = -65
    y = 43.33 student tkts

    x + y = 105
    x + 43.33 = 105
    x = 61.67 student tkts

    are you sure you typed this problem right?
    because there were 61.67 adult tkts
    and 43.33 student tkts

    the number of tkts should not be a fraction, but I checked this 4 times
