Jack's Convenience Store is open for 20 hours a day, Monday through Saturday. There is always one employee in the store. The store employs three fulltime employees, who work 40 hours per week and earn $9 per hour. The store also spends $200 per week on each full-time employee's benets. Their labor contract requires that they earn double-time for any overtime work and that any employee who works 30 hours or more per week be given full benets. The store is considering expanding its hours to 24 hours per day, Monday through Saturday, and 16 hours on Sunday. How much would it cost the store to expand its hours and have its current employees work overtime to cover the extra hours? m
