A washer and dryer cost $652 combined. The washer cost $48 less than the dryer. What is the cost of the dryer?
Levart [38]

Answer:

The dryer costs $350

Step-by-step explanation:

<u>Step 1:  Make a system of equations</u>

<em>w + d = 652</em>

<em>w = d - 48</em>

<em />

<u>Step 2:  Plug in the know w into the first equation</u>

d - 48 + d = 652

2d - 48 + 48 = 652 + 48

2d / 2 = 700 / 2

<em>d = 350</em>

<em />

Answer:  The dryer costs $350
