[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

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.
