A washer and dryer cost a total of . The cost of the washer is three times the cost of the dryer. Find the cost of each item.
Let's assume the cost of the dryer is $x.
The cost of the washer is then $3x.
The total cost of both items is the sum of the cost of the washer and the cost of the dryer: $3x + $x = $1500.
This can be simplified to 4x = $1500.
If we divide both sides of the equation by 4, we get x = $375.
Therefore, the cost of the dryer is $375 and the cost of the washer is $3(375) = $1125. Answer: \boxed{375, 1125}.
