Answer:

$375

Step-by-step explanation:

Given:

  • A washer and a dryer cost $669 combined.
  • The washer costs $81 less than the dryer.

To Find:

What is the cost of the dryer?

Solve:

Let's  the price of the washer is w and the price of the dryer is d.

Thus,

w + d = 669

d - 81 = w

To find the cost of the dryer, we just need to substitute it for w in the first equation:

(d - 81) + d = 669

2d - 81 = 669

2d = 750

d = 375

Hence the cost of the dryer is $375.
