Answer 2

Calculation of the Wholesale Price

To find the wholesale price, we need to determine the original price of the textbook before the 20% increase. Let's assume the retail price of the textbook is 180 rubles and it is 20% higher than the wholesale price.

Let's denote the wholesale price as x. The retail price is then given by x + 20% of x.

Mathematically, this can be expressed as: x + 0.2x = 180

Simplifying the equation, we have: 1.2x = 180

To find the value of x, we divide both sides of the equation by 1.2: x = 180 / 1.2

Calculating this, we find that the wholesale price of the textbook is 150 rubles.

Maximum Number of Textbooks that can be Purchased

Now, let's determine the maximum number of textbooks that can be purchased for 10,000 rubles at the wholesale price of 150 rubles per textbook.

To find the maximum number of textbooks, we divide the total amount available for purchase (10,000 rubles) by the wholesale price (150 rubles).

Mathematically, this can be expressed as: Maximum number of textbooks = 10,000 rubles / 150 rubles

Calculating this, we find that the maximum number of textbooks that can be purchased at the wholesale price is approximately 66 textbooks.

Therefore, you can buy a maximum of 66 textbooks at the wholesale price of 150 rubles each with 10,000 rubles.
