Question

A washer and a dryer cost $797 combined. The washer costs $47 more than the dryer. What is the cost of the dryer?

Answer 1

Answer:

$375

Explanation:

• Let the cost of the dryer = d

The washer costs $47 more than the dryer, therefore:

• The cost of the washer = d+47

The combined cost of the washer and dryer = $797

Therefore:

$\begin{gathered} Cost\; of\; \text{Washer}+\text{Cost of Dryer}=\ 797 \\ d+47+d=797 \\ 2d=797-47 \\ 2d=750 \\ \text{Divide both sides by 2} \\ \frac{2d}{2}=\frac{750}{2} \\ d=\ 375 \end{gathered}$

The cost of the dryer is $375.
