ANSWER:
$425
STEP-BY-STEP 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:
[tex]\begin{gathered} w+d=911 \\ \\ w=d+61 \end{gathered}[/tex]We substitute the second equation into the first and solve for d, like this:
[tex]\begin{gathered} d+61+d=911 \\ \\ 2d=911-61 \\ \\ d=\frac{850}{2} \\ \\ d=\text{\$}425 \end{gathered}[/tex]Therefore, the price of the dryer is $425.
