Question

)Hannah's electricity company charges her $0.15 per kWh (kilowatt-hour) of electricity, plus a basic connection charge of $25.00 per month. Write a linear function that models her monthly electricity bill as a function of electricity usage.

Answer 1

Linear function: y = 24x + 25

Explanation:

24 hours = 1 day

30 days = 1 month

0.15 x 24 = 6

30 x 6 = 180

180 + 25 = 205

Linear function: y = 24x + 25

Hope this helps! :)
