Calculation of the Percentage Change in Pasta Prices

To determine the percentage change in the price of pasta, we can use the formula:

Percentage Change = ((New Value - Old Value) / Old Value) * 100

Given that the total consumption of pasta increased by 10% and the revenue of pasta producers increased from 500 million rubles to 660 million rubles, we can calculate the percentage change in the price of pasta.

Let's assume the initial price of pasta was P rubles.

The initial revenue can be calculated as follows: Initial Revenue = Initial Price * Initial Consumption

The final revenue can be calculated as follows: Final Revenue = Final Price * Final Consumption

Since the total consumption of pasta increased by 10%, the final consumption can be calculated as follows: Final Consumption = Initial Consumption + (0.1 * Initial Consumption)

Given that the initial revenue was 500 million rubles and the final revenue was 660 million rubles, we can set up the following equation: Initial Price * Initial Consumption = 500 million rubles Final Price * Final Consumption = 660 million rubles

Substituting the values, we have: P * Initial Consumption = 500 million rubles Final Price * (Initial Consumption + (0.1 * Initial Consumption)) = 660 million rubles

Simplifying the equations, we get: P = 500 million rubles / Initial Consumption Final Price = 660 million rubles / (Initial Consumption + (0.1 * Initial Consumption))

Now, we can calculate the percentage change in the price of pasta using the formula mentioned earlier.

Please provide the initial consumption of pasta for further calculations.
