    Let the cost of the dryer be x.

    Since the washer is 3 * the cost of dryer = 3*x = 3x

    The total cost = $1000

    x + 3x = 1000

    4x = 1000

    x = 1000/4

    x = 250

    Since the cost of the dryer be x, x = 250

    Cost of dryer = $250.

    Hope this explains it.

    [tex] W + D = 1000 / /

    W = 3*D [tex]

    Plug the second equation into the first;

    [tex] W+D=1000 / /

    (3*D) + D=1000//

    4D=1000 [tex]

    D = $250
