Question

Need this last one and I'm set.

A washer and a dryer cost $1000 combined. The cost of the washer is three times the cost of the dryer. What is the cost of the dryer?

Answer 1

The cost of the dryer = d
The cost of the washer = w
Can you express the cost of the washer in terms of the dryer?
w = ?

Answer 2

you set it up like this: Washer=W, Dryer=D
1000=W+D
W=3D
so 1000=D+3D or 1000=4D
divide both sides by 4 and we get D=250
so Dryer = $250 and Washer = $750
