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.
