Question

A washer and a dryer cost $687 combined. The washer costs $37 more than the dryer. What is the cost of the dryer?

Answer 1

`$325`

Explanation:

Let's say that the cost of the dryer is `d`.

This means that:

`d+(d+37)=687`

Where `(d+37)` is the cost of the washer

Simplify it:

`2d+37=687`

And solve it:

`2d=687-37`

`2d=650`

`d=650/2`

`d=325`

Answer 2

The washer costs $362 and the dryer costs $325 dolars.

Explanation:

There is probably an easier way to do this, but here's how I did it:
First I took $37 off the total cost, because we know that the washer costs $37 more then the dryer.
Then I devided the answer by two and added the $37 to the cost for the washer.

The sum:
687 - 37 = 650
650 / 2 = 325 (price of dryer)
325 + 37 = 362 (price of washer)
