20 рублей это 100%, тогда 1%=20/100=0,2 рубля. 10%=0,2*10=2 рубля, значит ручка стала стоить 20+2=22 рубля. 700/22=31,8, но нужно учитывать, что купить только кусок ручки мы не можем) поэтому ответ 31

Answer 3

Calculating the Maximum Number of Pens

To calculate the maximum number of pens that can be purchased with 700 rubles after a 10% price increase, we need to follow these steps:

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

Let's calculate it step by step:

1. Price after the 10% increase: - The original price of the pen is 20 rubles. - The price increase is 10% of 20 rubles, which is 2 rubles. - The new price of the pen is 20 rubles + 2 rubles = 22 rubles.

2. Maximum number of pens that can be purchased: - The total budget is 700 rubles. - Divide the total budget by the price of a pen to find the maximum number of pens: 700 rubles / 22 rubles = 31.82 pens.

Since we cannot purchase a fraction of a pen, the maximum number of pens that can be purchased is 31 pens.

Please note that the calculation assumes that the price increase applies to all pens and that there are no other factors affecting the purchase.
