Final answer:
To formulate a function that models an electric bill as a function of electricity usage (k), we can use the charges involved and the given information. The function is Electric Bill(k) = ($0.28 * k) + $35.
Step-by-step explanation:
To formulate a function that models an electric bill as a function of electricity usage (k), we need to consider the charges involved. The utility company charges $0.28 per kilowatt hour of electricity and a $35 basic connection fee each month. Let's break it down step by step:
- The charge for electricity usage is $0.28 multiplied by the number of kilowatt hours (k).
- The basic connection fee of $35 is a fixed amount that needs to be added to the electricity charge.
- Finally, the total bill is the sum of the electricity charge and the basic connection fee.
Combining all these steps, the function that models the electric bill can be represented as:
Electric Bill(k) = ($0.28 * k) + $35
