Question

A washer and dryer cost $911 combined the washer cost $61 more than the dryer. What is the cost of the dryer?

Answer 1

$425

Explanation:

Let w be the price of the washer and d be the price of the dryer, we can establish the following system of equations:

`\begin{gathered} w+d=911 \\ \\ w=d+61 \end{gathered}`

We substitute the second equation into the first and solve for d, like this:

`\begin{gathered} d+61+d=911 \\ \\ 2d=911-61 \\ \\ d=(850)/(2) \\ \\ d=\text{\$}425 \end{gathered}`

Therefore, the price of the dryer is $425.
