Assuming an air conditioner is used for 137 days, what is the total number of kWh consumed at 7.25 kWh per hour?

To find the total number of kilowatt-hours (kWh) consumed by the air conditioner over 137 days at a consumption rate of 7.25 kWh per hour, we need to first calculate the total hours the unit operates over the specified period.

Since there are 24 hours in a day, the total number of hours for 137 days can be determined by multiplying 137 days by 24 hours per day:

[

137 \text{ days} \times 24 \text{ hours/day} = 3288 \text{ hours}

]

Next, we can calculate the total energy consumed in kWh by multiplying the number of hours by the hourly consumption rate of the air conditioner:

[

3288 \text{ hours} \times 7.25 \text{ kWh/hour} = 23838 \text{ kWh}

]

This calculation shows that the air conditioner would consume a total of 23838 kWh over 137 days when running continuously. The correct answer reflects the accurate multiplication of the total hours and the consumption rate. Therefore, the correct option is the one indicating 23838 kWh per year, as it aligns with the calculated total energy consumption for the entire period of use
