Problem Analysis

We are given that a notebook costs 40 rubles and we have 550 rubles to spend after a 15% price reduction. We need to determine the maximum number of notebooks we can buy with this amount.

Solution

To find the maximum number of notebooks we can buy, we need to divide the total amount of money we have by the cost of each notebook. However, since the price of the notebook has been reduced by 15%, we need to calculate the new price first.

Let's calculate the new price of the notebook after the 15% reduction: - Original price: 40 rubles - Reduction: 15% - New price = Original price - (Original price * Reduction) - New price = 40 - (40 * 0.15) - New price = 40 - 6 - New price = 34 rubles

Now, we can calculate the maximum number of notebooks we can buy with 550 rubles: - Maximum number of notebooks = Total amount of money / New price - Maximum number of notebooks = 550 / 34 - Maximum number of notebooks ≈ 16.18

Since we cannot buy a fraction of a notebook, we can only buy a whole number of notebooks. Therefore, the maximum number of notebooks we can buy is 16.

Answer

The maximum number of notebooks that can be bought for 550 rubles, after a 15% price reduction, is 16 notebooks.
