Answer:
$620
Step-by-step 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
