Mrs. Klein made some tarts. She sold three fifths of them in the morning and one fourth the remainder in the afternoon. If she sold 200 more tarts in the morning than in the afternoon how many tarts did she make?

  • Math -

    number of tarts ---- x
    number sold in morning = 3x/5
    leaving 2x/5
    number sold in afternoon = (1/4)(2x/5) = x/10

    3x/5 = x/10 + 200
    times 10
    6x = x + 2000
    5x = 2000
    x = 400

    check:
    sold in morning = (3/5)(400) = 240
    leaving 160
    she sold 1/4 of 160 or 40 in the afternoon
    Did she sell 200 more in the morning? YES
    Answer is correct!
