Calculation of the Amount Paid by Petya for February

To calculate the amount paid by Petya for February, we need to consider the increase in the price per liter and the decrease in the number of liters consumed.

Let's break down the information given:

- In January, Petya paid 800 rubles for hot water. - In February, the price per liter increased by 20%. - Petya consumed 30% fewer liters in February compared to January.

To calculate the amount paid by Petya for February, we can follow these steps:

1. Calculate the new price per liter in February by adding 20% to the original price per liter. 2. Calculate the number of liters consumed in February by subtracting 30% from the number of liters consumed in January. 3. Multiply the new price per liter in February by the number of liters consumed in February to get the total amount paid by Petya for February.

Let's perform the calculations:

1. Calculate the new price per liter in February: - Original price per liter: Not provided in the given information. - We don't have the original price per liter, so we cannot calculate the new price per liter in February.

2. Calculate the number of liters consumed in February: - Number of liters consumed in January: Not provided in the given information. - We don't have the number of liters consumed in January, so we cannot calculate the number of liters consumed in February.

3. Calculate the total amount paid by Petya for February: - New price per liter in February: Not calculated. - Number of liters consumed in February: Not calculated. - We don't have the necessary information to calculate the total amount paid by Petya for February.

Unfortunately, without the original price per liter and the number of liters consumed in January, we cannot calculate the amount paid by Petya for February.
