Amy had 20% more money than John. After she spent 50% of her money, she had $72 less than John. How much money had she left?

  • maths -

    John has $X.
    Amy had X + 0.2X = $1.2X.

    1.2x/2 = x - 72,
    0.6x = x - 72,
    x - 0.6x = 72,
    0.4x = 72,
    X = $180. = John's Amt.
    X - 72 = 180 - 72 = $108 = Amy,s bal.
