Let x equal the original price. Solve for x

0.8x = 12,590

We'll be glad to check your answer.

.8x/.8 = 12,590/.8

x= 15,737.50

But where did you get 0.8 from?

Yes. Your answer is correct. The original price of the car was $15,737.50.

I used 0.8 because with a 20% discount, the customer pays 80% (or 0.8) of the original price.
