Question

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

Answer 1

The dryer costs $350

Explanation:

Step 1: Make a system of equations

w + d = 652

w = d - 48

Step 2: Plug in the know w into the first equation

d - 48 + d = 652

2d - 48 + 48 = 652 + 48

2d / 2 = 700 / 2

d = 350

Answer: The dryer costs $350
