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 1

Answer:150

Step-by-step explanation:

600/4=150  (150)3=450  450+150=600

Answer 2

Answer: 150 dollars

Step-by-step explanation: Because the dryer is equal to washer divided by 3 you can substitute Washer/3 in the equation

W+ W/3=600

multiply both sides by 3

3W+W=1800

4W=1800

Divide both sides by 4

The answer to W is 450 dollars which you then divide by three to get 150 dollars
