If a business operates 10 hours a day, Monday to Friday, and 5 hours on Saturday, what would be its monthly consumption if its constant demand is 10kW?

To determine the monthly energy consumption of a business with a constant demand of 10 kW and specific operating hours, it is essential to calculate the total hours the business operates in a week and then extrapolate that to a month.

First, calculate the daily operation hours during the week:

• From Monday to Friday, the business operates 10 hours a day for 5 days, which equals 50 hours.

• On Saturday, the business operates for 5 hours.

Adding these together gives:

50 hours (Monday to Friday) + 5 hours (Saturday) = 55 hours per week.

Next, to determine the monthly operation, we typically calculate based on a 4-week month:

55 hours/week * 4 weeks = 220 hours per month.

Now, with a constant demand of 10 kW, we can find the monthly energy consumption in kilowatt-hours (kWh):

220 hours * 10 kW = 2200 kWh.

This calculation illustrates how the constant demand over the operating hours translates into total energy consumption for the month, confirming that the correct choice is 2200 kWh.
