Question

A washer and dryer cost $677 combined. The washer cost $73 less than the dryer. What is the cost to f the dryer

Answer 1

Explanation:

Let's assume that the dryer costs x $.

Then the washer costs x-73$, 73$ dollars less.

If we add the two costs together we get that: x+x-73 = 677 <-> 2*x = 750 <-> x=375$

The dryer costs x=375$

Answer 2

The cost of the dryer is $375

Explanation:

We call w the cost of the washing machine and we call d the cost of the dryer

We know that together they cost $ 677

This means that:

`w + d = 677`

We also know that the washer cost $ 73 less than the dryer

This means that:

`w = d-73`

Now we substitute the second equation in the first and solve for d:

`d-73 + d = 677`

`2d= 677+73`

`2d=750`

`d=(750)/(2)`

`d=\$\ 375`
