Question

Свитер стоил 800 рублей. Цена на него последовательно повышалась 2 раза на 10 %. Какой стала цена свитера после 2 повышения?

Answer 1

$800* \frac{11}{10}* \frac{11}{10} =968$Ответ:968 рублей

Answer 2

10%=0,1
800*0,1=80(руб)  - на столько повысилась цена 1раз
800+80=880(руб) - цена после 1 повышения цен
880*0,1=88(руб)  - на столько повысилась цена 2 раз
880+88=968(руб) - цена свитера после второго повышения цен

Answer 3

Calculating the Price Increase of the Sweater

To calculate the final price of the sweater after two consecutive 10% increases, we can use the following steps:

1. Initial Price of the Sweater: The sweater initially cost 800 rubles. 2. First Price Increase: The price increased by 10%. 3. Second Price Increase: The resulting price from the first increase is then increased by another 10%.

Calculation Steps

1. Initial Price: 800 rubles. 2. First Increase: 10% of 800 rubles is 80 rubles. So, the price after the first increase is 800 + 80 = 880 rubles. 3. Second Increase: 10% of 880 rubles is 88 rubles. So, the price after the second increase is 880 + 88 = 968 rubles.

Therefore, the final price of the sweater after two consecutive 10% increases is 968 rubles. This calculation is based on the initial price of 800 rubles and two consecutive 10% increases
