Lexi and Maria had $250 altogether. After Lexi spent 2 over 5 of her money and Maria spent $40, they had the same amount of money left. How much money did Lexi have in the beginning?

  • math - , Thursday, November 14, 2013 at 10:29pm

    Lexi's amount --- x
    Maria's amount --- 250-x

    Lexi spent 2/5 of x, so she has 3x/5 left
    Maria spends 40, so she has 250-x-40 or 210-x left

    3x/5 = 210-x
    times 5 to get rid of fractions
    3x = 1050 - 5x
    8x = 1050
    x =131.25

    So Lexi had $131.25 and Maria had 118.75

    check:
    Lexi spent 2/5 of 131.25 , leaving her with 78.75
    Maria spent 40 of her 118.75 , leaving her with 78.75
    YEahhh
