The original price is $15737.50.

Explanation:

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#

So 1% of the original price is 157.375. Now we can find what 100% of the original price was by multiplying it by 100.

#157.375xx100=15737.5#

And since it is a monetary value, we add an extra 0 at the end to make it 2 decimal places. So the original price was $15737.50.
