Answer 2

Calculation of the Maximum Number of Pens

To calculate the maximum number of pens that can be purchased for 300 rubles after a 40% price increase, we need to follow these steps:

1. Determine the price of a pen after the price increase. 2. Divide the total budget of 300 rubles by the price of a pen after the increase to find the maximum number of pens that can be purchased.

Let's calculate it step by step:

1. Determine the price of a pen after the price increase: - The original price of a pen is 15 rubles. - The price increase is 40%. - To calculate the new price, we need to add 40% of the original price to the original price. - The new price of a pen after the increase is 15 + (15 * 0.4) = 15 + 6 = 21 rubles.

2. Divide the total budget of 300 rubles by the price of a pen after the increase: - The total budget is 300 rubles. - The price of a pen after the increase is 21 rubles. - To find the maximum number of pens, we divide the total budget by the price of a pen after the increase: 300 / 21 = 14.2857.

Therefore, the maximum number of pens that can be purchased for 300 rubles after a 40% price increase is approximately 14 pens.

Please note that the result is an approximation due to the decimal value obtained in the calculation.
