Calculation of Percentage Decrease in Prices

To calculate the percentage decrease in prices of gingerbread cookies in the two magical cities, let's consider the following information:

- In magical city A, the prices of gingerbread cookies decreased by 15% in rubles and 10% in dollars. - In magical city B, the prices of gingerbread cookies decreased by 32% in rubles.

We need to find the percentage decrease in prices in dollars in magical city B.

Let's assume the original price of gingerbread cookies in both cities is 100 units.

In magical city A: - The price decreased by 15% in rubles, which means the new price in rubles is 85 units. - The price decreased by 10% in dollars, which means the new price in dollars is 90 units.

In magical city B: - The price decreased by 32% in rubles, which means the new price in rubles is 68 units.

To find the percentage decrease in dollars in magical city B, we need to compare the new price in dollars in magical city A (90 units) with the new price in rubles in magical city B (68 units).

The percentage decrease in dollars can be calculated using the formula:

Percentage decrease = ((New price in dollars - New price in rubles) / New price in dollars) * 100

Let's calculate the percentage decrease:

Percentage decrease = ((90 - 68) / 90) * 100 = 24.44%

Therefore, the prices of gingerbread cookies in magical city B decreased by approximately 24.44% in dollars for Christmas.

Please note that the calculations above are based on the assumption that the original price of gingerbread cookies in both cities is 100 units. The actual percentage decrease may vary depending on the original prices.
