peter has 3 different kinds of buttons in one box. there are 124 more ivory buttons than plastic buttons and 1/3 as many wooden buttons as ivory buttons. there are 72 wooden buttons. how many plastic buttons are there?

  • math -

    x plastic buttons
    (x + 124) ivory
    1/3(x + 124) wooden

    1/3(x + 124) = 72
    Multiply both sides by 3:
    x + 124 = 72
    x = 92 plastic buttons
