    R = robins cans

    s = sara's cans

    n = nick's cans

    T = total cans

    s = 5r

    n = 6r

    T = 216 = s + r + n

    we sub in the first two equations into the first

    216 = 5r + 6r + r

    216 = 12r

    r = 18

    sub this back into equations 1 and 2

    thus

    r = 18

    s = 90

    n = 108
