Answer 1

Было 100 %. В сентябре 80% т. к снизили на 20 %.
а потом эту же цену повысили на 10%. т.е (80*10)/100=8 значит повысили на 8 .
точнее 80+8=88% следовательно за 2 месяца цена понижена на 12 %

Answer 2

Calculation of Price Change

To calculate the change in price over the two-month period, we need to consider the initial price and the subsequent changes in September and October.

Let's assume the initial price of the product is 100 units.

In September, the price of the product decreased by 20%. - The price decreased by 20% of 100 units, which is 20 units. - Therefore, the price in September was 100 units - 20 units = 80 units.

In October, the price of the product increased by 10%. - The price increased by 10% of 80 units, which is 8 units. - Therefore, the price in October was 80 units + 8 units = 88 units.

To determine the overall change in price over the two-month period, we compare the final price (88 units) with the initial price (100 units).

The overall change in price is calculated as follows: - Change in price = (Final price - Initial price) / Initial price * 100% - Change in price = (88 units - 100 units) / 100 units * 100% - Change in price = -12 units / 100 units * 100% - Change in price = -12%

Therefore, the price of the product decreased by 12% over the two-month period compared to the initial price.

Please note that the calculations are based on the assumption that the initial price is 100 units and the subsequent changes are as stated in the question.
