A washer and a dryer cost 1000$ combined. The cost of the washer is three times the cost of the dryer. What is the cost of the dryer?

$250

Step-by-step explanation:

250 x 4 is 1000 and the washer is 3 times as more as the dryer.

The cost of the dryer is $250 and the cost of the washer is $750

Step-by-step explanation:

The ratio that is presented is Dryer 1: Washer 3 (1:3).

So, when you multiply $250x3 plus the $250 for the dryer you get $1000.

You can use the equation A+(Ax3)=$1000

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
