В соответствии с принятыми в магазине правилами цена товара в течение недели остается неизменной,а в первый день каждой следующей недели снижается на 20% от предыдущей цены. сколько рублей будет стоить товар на 17 день после поступления в продажу

Answer 1

Цена товара уменьшалась два раза на 8 и на 15 день, то есть
1300*0.20=1040-цена товара на 8 день
1040*0.20=832-цена товара на 15 день
Значит, на 17 день товар стоил 832 р.

Answer 2

Calculation of the Price of the Item on the 17th Day

To calculate the price of the item on the 17th day after it was put up for sale, we need to consider the following information:

- The initial price of the item is 1300 rubles. - The price remains unchanged during the first week. - On the first day of each subsequent week, the price is reduced by 20% of the previous price.

Let's break down the calculation step by step:

1. The price of the item on the first day is 1300 rubles. 2. On the eighth day (the start of the second week), the price is reduced by 20% of the previous price: - 1300 rubles - (20% of 1300 rubles) = 1300 rubles - (0.2 * 1300 rubles) = 1300 rubles - 260 rubles = 1040 rubles. 3. On the fifteenth day (the start of the third week), the price is reduced by 20% of the previous price: - 1040 rubles - (20% of 1040 rubles) = 1040 rubles - (0.2 * 1040 rubles) = 1040 rubles - 208 rubles = 832 rubles. 4. Finally, on the seventeenth day, the price remains the same as on the fifteenth day, which is 832 rubles.

Therefore, the price of the item on the 17th day after it was put up for sale will be 832 rubles.
