Answer 2

Calculation of Cost per Kilowatt-hour

To find the cost per kilowatt-hour (kWh) of electricity, we can use the information provided. It states that 55 kilowatt-hours of electricity were paid for 2.2 rubles.

To calculate the cost per kilowatt-hour, we can divide the total cost by the number of kilowatt-hours:

Cost per kilowatt-hour = Total cost / Number of kilowatt-hours

In this case, the total cost is 2.2 rubles and the number of kilowatt-hours is 55. Plugging these values into the formula, we get:

Cost per kilowatt-hour = 2.2 rubles / 55 kilowatt-hours

Calculating this, we find that the cost per kilowatt-hour of electricity is approximately 0.04 rubles per kilowatt-hour.

Calculation for 75 Kilowatt-hours

To find the cost for 75 kilowatt-hours of electricity, we can use the cost per kilowatt-hour we calculated earlier.

To calculate the total cost, we can multiply the number of kilowatt-hours by the cost per kilowatt-hour:

Total cost = Number of kilowatt-hours * Cost per kilowatt-hour

In this case, the number of kilowatt-hours is 75. Plugging this value into the formula, we get:

Total cost = 75 kilowatt-hours * 0.04 rubles per kilowatt-hour

Calculating this, we find that the cost for 75 kilowatt-hours of electricity is approximately 3 rubles.

Therefore, the cost for 75 kilowatt-hours of electricity is approximately 3 rubles.

Please note that the provided information does not specify the exact pricing structure or any additional charges that may be applicable. The calculation above assumes a simple cost per kilowatt-hour without any additional factors.
