Question

A washer and a dryer cost $600 combined. the cost of the washer is three times the cost of the dryer. what is the cost of the dryer? answer

Answer 1

Greetings!

We can solve this by creating an algebraic equation.

`3d+d=600`

`d=dryer`

Solve for d.

`4d=600`
Divide both sides by 4.

`(4d)/4=(600)/4`
The Answer Is:

`d=150`

To Check:

`w+150=600`
Add -150 to both sides.

`(w+150)+(-150)=(600)+(-150)`

`w=450`

`150*3=450`

The Dryer cost $150.

Hope this helps.
