The price of a book was $400. If the book's price is decreased by 15% and then increased by 40%, what is the final price of the book?
Please answer the following question by reasoning step-by-step.
476
When the price of the book is decreased by 15%, the total price decrease is 15 / 100 * $400 = $60.

The new price of the book becomes $400 - $60 = $340.

The price of the book is then increased by 40 / 100 * 340 = $136.

The final price of the book is $340 + $136 = $476.

.

So, the final answer is 476
