A washer and a dryer cost $930 combined. The washer costs $80 more than the dryer. What is the cost of the dryer?
Let's assume the cost of the dryer is D.
According to the information given, the washer costs $80 more than the dryer, so the cost of the washer is D + $80.
Since the combined cost of the washer and dryer is $930, we can set up the following equation:
D + (D + $80) = $930
2D + $80 = $930
2D = $930 - $80
2D = $850
D = $850 / 2
D = $425
Therefore, the cost of the dryer is $425.
