Question

Цену на товар сначала повыфсели на 10% а затем ещё на 15%. На сколько процентов повысилась цена по сравнению с перваначальной

Answer 1

Цена повысилась на 26,5 процентов. 10+15+1,5=26,5

Answer 2

Calculation of Price Increase

To calculate the final price after two successive increases of 10% and 15%, we can use the following formula:

Final Price = Initial Price * (1 + First Increase) * (1 + Second Increase)

Let's assume the initial price is P.

The first increase of 10% can be represented as 0.1.

The second increase of 15% can be represented as 0.15.

Using the formula above, we can calculate the final price as follows:

Final Price = P * (1 + 0.1) * (1 + 0.15)

Simplifying the equation:

Final Price = P * 1.1 * 1.15

Now, let's calculate the percentage increase in price compared to the initial price:

Percentage Increase = (Final Price - Initial Price) / Initial Price * 100

Substituting the values:

Percentage Increase = (P * 1.1 * 1.15 - P) / P * 100

Simplifying the equation:

Percentage Increase = (1.265 * P - P) / P * 100

Percentage Increase = 0.265 * P / P * 100

Percentage Increase = 26.5%

Therefore, the price has increased by 26.5% compared to the initial price.
