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 7000 rubles, we need to consider the wholesale price and the 20% markup.

Given: - Wholesale price of the textbook: 170 rubles - Retail price is 20% higher than the wholesale price

To find the retail price, we can calculate 120% of the wholesale price using the formula:

Retail price = Wholesale price + (Wholesale price * 20%)

Let's calculate the retail price first:

Retail price = 170 + (170 * 20%)

To calculate 20% of 170, we can multiply 170 by 0.2:

Retail price = 170 + (170 * 0.2)

Retail price = 170 + 34

Retail price = 204 rubles

Now, we can calculate the maximum number of textbooks that can be purchased at the retail price of 7000 rubles:

Maximum number of textbooks = Total budget / Retail price

Maximum number of textbooks = 7000 / 204

To calculate this, we can use the division operator:

Maximum number of textbooks = 7000 / 204

Calculating this, we find that the maximum number of textbooks that can be purchased at the retail price of 7000 rubles is approximately 34.31 textbooks.

Please note that since textbooks cannot be purchased in fractions, the maximum number of textbooks that can be purchased is 34 textbooks.

Therefore, the maximum number of textbooks that can be purchased at the retail price of 7000 rubles is 34 textbooks.

Answer:

The maximum number of textbooks that can be purchased at the retail price of 7000 rubles is 34 textbooks.
