Question

Mrs. Atkins pays $1800 for a new refrigerator, washer and dryer. The refrigerator cost $250 more then the washer. The dryer cost half as much as the washer how much does the washer cost?

Answer 1

$620

Explanation:

Let the price of refridgerator be "r"

price of washer be "w"

and

price of dryer be "d"

Total 1800, that means, we can write:

r + w + d = 1800

Also, refrigerator cost 250 more than washer, so we can write:

r = w + 250

The dryer is HALF (0.5) of washer, so we can write:

d = 0.5w

Now, we replace equation1 with equation 2 & 3, so get an equation in "w" and solve for w:

r + w + d = 1800

w + 250 + w + 0.5w = 1800

2.5w + 250 = 1800

2.5w = 1800 - 250

2.5w = 1550

w = 1550/2.5

w = 620

Thus, the washer costed $620
