Ryan saved $55 more than Jim. Chris saved 6 times as much as Jim. Donna saved half as much as Chris. If the children saved $3245 altogether how much did each child save?

  • Math - ,

    R = J + 55
    C = 6 J
    C = 2 D
    R + J + C + D = 3245

    Four equations; four unknowns.
    J + 55 + J + 2D + D = 3245
    2J + 3D = 3190
    C/3 + (3/2) C = 3190
    (11/6)C = 3190
    C = 1740
    J = 290
    D = 870
    R = 345
