math: bobby has $14 more than tina while seda has twice as much money as bobby. together they have $208. how much money does each have?

  • algebra - ,

    T + T + 14 + 2(T + 14) = 208

    4T + 42 = 208

    4T = 166

    T = 41.50

    Tina: 41.50
    Bobby: 55.50
    Seda: 111.00

  • algebra - ,

    Bobby = x+14
    Tina = x
    Seda = 2(x+14)

    x+14+x+2x +28 = 208
    4x + 42= 208
    4x + 42-42= 208 -42
    4x = 166
    4x/4 = 166/4
    x = 41.50
    Tina = $ 41.50
    Bobby =$ 55.50
    Seda = $ 111

  • algebra - ,
