Question

A washer and a dryer cost $639 combined. The washer costs $61 less than the dryer. What is the cost of the dryer?

Answer 1

$350

Explanation:

Let d = price of dryer

Then d - 61 is the price of the washer.

The sum of the prices is $639.

d + d - 61 = 639

2d - 61 = 639

2d = 700

d = 350

The price of the dryer is $350
