Final answer:
The total electrical energy consumed over 30 days can be calculated by dividing the total cost of the electricity bill by the cost per kilowatt hour. Here, with a bill of $71 and a rate of $0.13 per kWh, the total energy consumed is 546.15 kWh.
Step-by-step explanation:
To calculate the total amount of electrical energy consumed in kilowatt-hours (kWh), we use the cost of electrical energy per kilowatt hour provided by the utility company and the total cost of the electricity bill. The given cost of electrical energy is $0.13 per kWh, and the total electricity bill for 30 days is $71.
To find out the energy consumed, we use the formula:
Total Energy Consumed (in kWh) = Total Cost of Electricity / Cost per Kilowatt Hour
Therefore, the total energy consumed is:
Total Energy Consumed = $71 / $0.13 per kWh
Total Energy Consumed = 546.15 kWh
So, the electrical energy consumed over the 30 days is 546.15 kWh.
