Question

Розничная цена учебника 180 рублей, она на 20% выше оптовой цены. Какое наибольшее число таких учебников можно купить по оптовой цене на 10 000 рублей?

Answer 1

1. 100+20 = 120% (цена розничной продажи по отношению к оптовой) 
2. 180:120*100 = 150р. (оптовая цена) 
3. 10000:150 = 66 шт. +остаток 100р. (наибольшее число учебников) 
ОТВЕТ: можно купить 66 штук. 

Answer 2

Calculation of the Optimal Number of Textbooks

To find the maximum number of textbooks that can be purchased at the wholesale price of 10,000 rubles, we need to determine the wholesale price of each textbook and then divide the total amount available for purchase by the wholesale price.

Given that the retail price of the textbook is 180 rubles and it is 20% higher than the wholesale price, we can calculate the wholesale price as follows:

Wholesale price = Retail price / (1 + Markup percentage)

Wholesale price = 180 / (1 + 0.2)

Wholesale price = 180 / 1.2

Wholesale price = 150 rubles

Now, we can calculate the maximum number of textbooks that can be purchased at the wholesale price of 10,000 rubles:

Maximum number of textbooks = Total amount available for purchase / Wholesale price

Maximum number of textbooks = 10,000 / 150

Maximum number of textbooks ≈ 66.67

Since we cannot purchase a fraction of a textbook, the maximum number of textbooks that can be purchased at the wholesale price of 10,000 rubles is 66 textbooks.

Please note that the actual number of textbooks that can be purchased may be slightly lower due to rounding or other factors.
