Question 125004: The sales price of a car is $12,590, which is 20% off the original price. What is the original price?
This just for practice. I wonder how they get $15737.90
$14,310.40
$14,990.90
$15,290.70
$15,737.50
$16,935.80
Answer by checkley71(8403)   (Show Source):
You can put this solution on YOUR website! If you want to find a reduction of 20% and you don't have the original number, then you need to assign the original price an unknown(x)and subtract 20% from x.
Thus we have the following equation.
--------------------------------------------------------------------
(X-.2X)=12,590 SALE PRICE MINUS 20% OF THIS PRICE EQUALS $12,590.
.8X=12,590
X=12,590/.8
X=$15,737.50 WAS THE ORIGINAL PRICE.
