Question

В течение января цена на яблоки выросла на 30%, а в течение февраля  - на 20%. На сколько процентов поднялась цена за 2 месяца?

Answer 1

Calculation of the Price Increase

To calculate the percentage increase in price over two months, we need to find the cumulative increase in price.

The price of apples increased by 30% in January and by 20% in February. To find the cumulative increase, we can use the following formula:

Cumulative Increase = (1 + Percentage Increase in January) * (1 + Percentage Increase in February) - 1

Let's calculate the cumulative increase:

Cumulative Increase = (1 + 0.30) * (1 + 0.20) - 1

Cumulative Increase = 1.30 * 1.20 - 1

Cumulative Increase = 1.56 - 1

Cumulative Increase = 0.56

Therefore, the price of apples increased by 56% over the two-month period.
