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

Let the cost of the dryer be x. Then the cost of the washer is 3x. According to the problem, the total cost is $600, so:

x + 3x = 600

4x = 600

Divide both sides by 4:

x = 150

Therefore, the cost of the dryer is $150.
