A washer and dryer cost a total of $924. The cost of the washer is two times the cost of the dryer. Find the cost of each item.

marshall27 [118]

Answer:

Washer = $616, Dryer = $308

Step-by-step explanation:

When something is twice the cost of something else but add up to be a total number that means 2/3rds is one item and 1/3 is the other.

924 / 3 = 308

308 * 2 = 616

308 + 616 = 924
