A washer and dryer costs $600 combined . The cost of the washer is three times to cost of the dryer whay is the cost of the dryer ?

Answer 1

First, set up your basic equations: W + D = $600, and W = $600 - D. Since the washer costs 3 times the cost of the dryer, we can say that the dryer costs 1/4 of the $600; therefore, dividing $600 by four, we get the cost of the dryer at $150. Since w = $600 - D, subtracting $150 from $600 gives us the cost of the washer of $450.

Answer 2

You need to create an equation to solve the problem.

Let the cost of the dryer be valued at X

Since the washer is 3 times the amount, make the washer 3X

dryer = x

washer = 3x

Add them together and set it equal to $600

x + 3x = 600

solve for x

x +3x = 600

4x = 600

x =150

Dryer = 150

Washer = 450
