Calculating the Maximum Number of Pens

To calculate the maximum number of pens that can be bought for 300 rubles after a 10% price increase, we can use the following steps:

1. Calculate the original price of the pen: - The original price of the pen is 40 rubles.

2. Calculate the new price of the pen after a 10% increase: - 10% of 40 is 4, so the price of the pen after a 10% increase is 40 + 4 = 44 rubles.

3. Determine the maximum number of pens that can be bought for 300 rubles: - 300 rubles divided by the new price of the pen (44 rubles) equals 6.818. - Since you can't buy a fraction of a pen, the maximum number of pens that can be bought for 300 rubles after a 10% price increase is 6.

Therefore, the maximum number of pens that can be bought for 300 rubles after a 10% price increase is 6 pens.
