To calculate the total bill, you need to consider both the usage charge and the customer charge.
-
Calculate the usage charge: \[ \text{Usage Charge} = \text{KWH used} \times \text{Rate per KWH} \] \[ \text{Usage Charge} = 648 , \text{KWH} \times 0.05954 , \text{USD/KWH} = 38.58592 , \text{USD} \]
-
Add the customer charge: \[ \text{Total Bill} = \text{Usage Charge} + \text{Customer Charge} \] \[ \text{Total Bill} = 38.58592 , \text{USD} + 2.85 , \text{USD} = 41.43592 , \text{USD} \]
Rounding to two decimal places, the total bill is approximately $41.44.
Among the given options, the closest amount is $41.43.
