Part A 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 f for the total rental cost of a vacuum cleaner. Hours 1 1.5 2 2.5 3 Cost ($) 20 23 26 29 32 A. f ( x ) = 6 x + 14 B. f ( x ) = 3 x + 14 C. f ( x ) = 3 x + 22 D. f ( x ) = 6 x + 24 Activity 2 of 2 Part B How much is the flat fee that the store charges? Flat fee the store charges = $

Two positive integers are 3 units apart on a number line. their product is 108. which equation can be used to solve for m, the greater integer? m(m – 3) = 108 m(m + 3) = 108 (m + 3)(m – 3) = 108 (m – 12)(m – 9) = 108
