in order to purchase a computer for the student activities office, the freshman class decides to raise 1/3 of the money and the sophomore class decides to raise 1/2 of the money. The student government association agrees to contribute to the rest which amounted to $400.what was the cost of the computer?

  • math -

    (1/3)x + (1/2)x + 400 = x

    (2/6)x + (3/6)x + 400 = x

    (5/6)x -x = -400

    -(1/6)x = -400

    x = 400/(1/6)

    x = 400 * 6

    x = 2400
