Question

A utilty company charges $0.12 per kilowatt-hour of electricity a customer with a solar panel generates that they don’t use themselves.

A customer has a charge of $82.04 and a credit of -$4.10 on this months bill.
1 - What is the amount due this month?
2 How many kilowatt-hours did they use?
3 How many kilowatt-hours did they generate that they didn’t use themselves?
4 What did a positive amount represent? What did a negative amount represent?

Answer 1

The amount due this month is $86.14. The customer used 683.67 kWh of electricity and did not generate any excess electricity. A positive amount represents a charge, while a negative amount represents a credit or refund.

Step-by-step explanation:

To calculate the amount due this month, we need to subtract the credit from the charge. In this case, the amount due is $82.04 - (-$4.10) = $86.14.

To find the kilowatt-hours used, we divide the charge by the rate of $0.12/kWh. The kilowatt-hours used is $82.04 / $0.12 = 683.67 kWh.

To determine the kilowatt-hours generated but not used, we need to subtract the kilowatt-hours used from the total charge. The kilowatt-hours generated but not used is 683.67 kWh - 683.67 kWh = 0 kWh.

A positive amount represents the charge for electricity used by the customer, while a negative amount represents a credit or refund given to the customer.
