MACHO ATE 125 HOT DOGS OVER A FIVE DAY PERIOD. EACH DAY HE AT SEVEN MORE HOT DOGS THAN ON THE PREVIOUS DAY. HOW MANY HOT DOGS DID HE EAT ON THE FIRST DAY?

  • MATH - ,

    first day --> x
    2nd day --> x+7
    etc

    x + x+7 + x+14 + x+21 + x+28 = 125
    5x = 55
    x = 11

  • MATH - ,

    x = (x+7) + (x+14) + (x+21) + (x+28) =
    125,
    5x + 70 = 125,
    5x = 125 - 70 = 55,
    x = 11.

  • MATH - ,

    I agree 100% with that answer and I understand all of it besides:
    5x + 70 = 125
    please help

  • MATH - ,

    X + (X + 7) + (X + 14) + (X + 21) + (X + 28) = 125.

    X + X + X + X + X = 5X.

    7 + 14 + 21 + 28 = 70.
    5X + 70 = 125
    5X = 125 - 70 = 55
    X = 11.

    I'm glad i could help.
