140+21=161р стоит учебник в магазине
3800:161=23.60 уч. можно купить 23 учебника и останется сдача 97р.

Answer 2

Calculation of the Maximum Number of Textbooks

To calculate the maximum number of textbooks that can be purchased at the retail price of 3800 rubles, we need to consider the wholesale price and the 15% markup.

The wholesale price of the textbook is 140 rubles The retail price is 15% higher than the wholesale price. Therefore, the retail price can be calculated as follows:

Retail Price = Wholesale Price + (15% of Wholesale Price)

Retail Price = 140 + (0.15 * 140) = 140 + 21 = 161 rubles

Now, we can calculate the maximum number of textbooks that can be purchased at the retail price of 3800 rubles:

Maximum Number of Textbooks = Retail Price / Retail Price of Each Textbook

Maximum Number of Textbooks = 3800 / 161 ≈ 23.60

Since we cannot purchase a fraction of a textbook, the maximum number of textbooks that can be purchased at the retail price of 3800 rubles is 23 textbooks.

Please note that the calculation assumes that the retail price is fixed at 15% higher than the wholesale price and does not consider any additional factors that may affect the pricing or availability of the textbooks.
