Answer 2

To calculate the amount the school paid for the books, we need to consider the discounts given by the bookstore. The bookstore offered a 15% discount on all books to all schoolchildren and students. Additionally, there was an additional 100% discount given to regular customers.

Let's break down the calculation step by step:

1. Calculate the amount of the 15% discount: - The original price of the books without any discount is 225,320 tenge. - To calculate the 15% discount, we multiply the original price by 0.15: 225,320 * 0.15 = 33,798 tenge.

2. Calculate the amount after the 15% discount: - Subtract the discount amount from the original price: 225,320 - 33,798 = 191,522 tenge.

3. Calculate the amount of the additional 100% discount for regular customers: - The additional 100% discount means that the school doesn't have to pay anything for the books. - Therefore, the amount after the additional discount is 0 tenge.

4. Calculate the final amount paid by the school: - Since the additional discount brings the amount to 0 tenge, the school paid 0 tenge for the books.

Therefore, the school paid 0 tenge for the books.

Please note that this calculation assumes that the discounts are applied in a sequential manner, with the 15% discount applied first and then the additional 100% discount for regular customers.
