Question

A washer and a dryer cost $581 combined. The washer costs $69 less than the dryer. What is the cost of the dryer?

Answer 1

Hi there!

So we know that the total would be $581 and so we also know that the washer cost 69 less than the dryer...

Let think...if we want to find the total, we should add 81 and 69 first...

`81+69=150`

Now we can subtract 362 by 150 as a try...

`362+150=512`

Now let try again...

If it would be 325 as the dryer, then the cost of the washer would be $69 less.

`325-69=256`

Ok so this means that if we add the two numbers, we’ll get 581 if it is right...

`256+325=581`

Perfect, so this means that the cost of the dryer is in fact 325$ and the washer would be the cost of 256$.
