Answer 2

Calculation of the original price of the books

To calculate the original price of the books without the discount, we need to subtract the discount amount from the final price.

Given: - Final price of the books: 43 rubles 25 kopeks - Discount rate: 13.5%

To calculate the discount amount, we multiply the final price by the discount rate and divide by 100: ``` Discount amount = (Final price * Discount rate) / 100 ```

Subtracting the discount amount from the final price will give us the original price: ``` Original price = Final price - Discount amount ```

Let's calculate the original price step by step:

1. Convert the final price to kopeks for easier calculation: - 43 rubles = 43 * 100 kopeks = 4300 kopeks - 25 kopeks

2. Calculate the discount amount: ``` Discount amount = (4300 kopeks * 13.5) / 100 = 580.5 kopeks ```

3. Subtract the discount amount from the final price: ``` Original price = 4300 kopeks - 580.5 kopeks = 3720.5 kopeks ```

4. Convert the original price back to rubles: - 3720 kopeks = 3720 / 100 rubles = 37 rubles 20 kopeks

Therefore, the books originally cost 37 rubles 20 kopeks without the discount.
