C(k) = 0.0682k + 8.32

Step-by-step explanation:

We have to find the function C(k) that models the amount Liana will pay for using k kilowatt-hours of electricity in one month.

Now, the ordered pair for the month of November and September are (550,45.83) and (1250,93.57) respectively.

Since she pays the same amount for every kilowatt-hour of electricity, so the function will be linear.

Hence, the equation can be written as

$\frac{C(k) - 93.57}{93.57 - 45.83} = \frac{k - 1250}{1250 - 550}$

⇒ $\frac{C(k) - 93.57}{47.74} = \frac{k - 1250}{700}$

⇒ C(k) - 93.57 = 0.0682k - 85.25

⇒ C(k) = 0.0682k + 8.32

Therefore, this is the function. (Answer)
