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?
Solve for x: 4x = 600, x = \( \frac{600}{4} \), x = 150
Step 1 :Let the cost of the dryer be x. Then the cost of the washer is 3x.
Step 2 :The combined cost is 600: x + 3x = 600
Step 3 :Solve for x: 4x = 600, x = \( \frac{600}{4} \), x = 150
