Final answer:
The cost of the dryer is $575 and the cost of the washer is $825.
Step-by-step explanation:
Let's assume the cost of the dryer is x dollars. Based on the information given, the washer costs $250 more than the dryer, so the cost of the washer is x + $250.
The total cost of the washer-dryer combination is $1400. We can set up the equation:
x + (x + $250) = $1400
Combining like terms, we get:
2x + $250 = $1400
Subtracting $250 from both sides, we get:
2x = $1150
Dividing both sides by 2, we find:
x = $575
Therefore, the cost of the dryer is $575 and the cost of the washer is $575 + $250 = $825.
