A washer and dryer costa total of $1160. The cost of the washer is three times the cost of the dryer. Find the cost of each item.

Well you would have to set up the equation first.

X is going to equal the price of the dryer.

The equation that would be set up then is 3x + x = 1160.

Then you add the common numerals, in this case 4x = 1160.

Then you would divide, which gives you x = 290

The dryer costs $290.

Then you would multiply the dryer price by 3, because the washer is 3 times as much as the dryer.

And finally, you get: Dryer = $290

Washer = $870

W = 3d

d + 3d = 1160

4d = 1160

d = 290

w = 290 x 3 = 870

answer

washer = $870

dryer = $ 290
