The sales price of a car is 12,590 which is 20% off the original price what is the original price

Another way to think about this is that $12590 is 80% of the original price. The original was 100%, but this price is 20% off so 100%-20%=80%. The way I like to think is that since I know 12590 is 80%, I can find how much 1% is by dividing 12590 by 80. 12590:80=157.375.
