HELP!! A hardware store rents vacuum cleaners that customers may use for part or all of a day, up to 12 hours, before returning. The store charges a flat fee plus an hourly rate. Write a linear function for the total rental cost of a vacuum cleaner. PLZ don't copy answers and I cant show the graph so search the question and you'll get the graph. Part A f(x) = 6x + 14

Part B

Flat fee the store charges = $

A reasonable domain for the function is:
Cost to rent a vacuum for 7 hours = $
