casey paid 32$ for a book that was on a sale of 20% off. what was the orhinal price for that book?

Answer 1

Let x be the original price of the book.

After a 20% discount, Casey paid 80% of the original price, which is 0.8x.

Given that Casey paid $32 for the book, we can write the equation:

0.8x = 32

Solving for x:

x = 32 / 0.8
x = 40

Therefore, the original price of the book was $40.
