Calculation of the Price After Two Price Changes

To determine the price of a product after two price changes, we need to follow the given sequence of changes: first a decrease of 20%, followed by an increase of 10%.

Let's assume the original price of the product is 500 rubles.

Step 1: Decrease of 20% To calculate the price after a 20% decrease, we need to multiply the original price by (100% - 20%) or 0.8.

500 rubles * 0.8 = 400 rubles

Step 2: Increase of 10% To calculate the price after a 10% increase, we need to multiply the price after the first change by (100% + 10%) or 1.1.

400 rubles * 1.1 = 440 rubles

Therefore, the price of the product after two changes is 440 rubles.
