Question

a washer and a dryer cost $450 combined. the cost of the washer is two times the cost of the dryer. what is the cost of the dryer? $150

Explanation:

Step1: Define variables

Let the cost of the dryer be \( x \). Then the cost of the washer is \( 2x \) (since the washer's cost is two times the dryer's).

Step2: Set up equation

The combined cost of the washer and dryer is $450, so we have the equation \( x + 2x = 450 \).

Step3: Solve the equation

Combine like terms: \( 3x = 450 \). Then divide both sides by 3: \( x=\frac{450}{3}=150 \).

Answer:

The cost of the dryer is $150.
