Hannahs electricity company charges her $0.11 per kilowatt-hour of electricity, plus a basic connection charge of $15 per month. Write a linear function that models her monthly electricity bill as a function of electricity usage.

C = 15 + 0.11y

Step-by-step explanation:

Let us assume that Hannah utilizes x kilowatt-hour of electricity per month.

The electricity company charges $ 0.11 per kilowatt-hour of electricity uses and plus a basic connection charge of $ 15.

Therefore, the linear function that models her monthly electricity bill (C) as a function of electricity usage (y) will be

C = 15 + 0.11y {Hence, C will be a linear function of y} (Answer)
