Emarpy Appliance is a company that produces all kinds of major appliances. Bud$$ Banis, the president of$$ Emarpy, is concerned about the production policy for the$$ company's best$-$selling refrigerator. The annual demand for this has been about $8500$ units each$$ year, and this demand has been constant throughout the year. The production capacity is $210$ units per day. Each time production$$ starts, it costs the company $$$$130$ to move materials into$$ place, reset the assembly$$ line, and clean the equipment. The holding cost of a refrigerator is $$$$51$ per year. The current production plan calls for $420$ refrigerators to be produced in each production run. Assume there are $250$ working days per year. $$f$)$ If Bud Banis wants to minimize the total annual inventory$$ cost$,$ how many refrigerators should be produced in each production$$ run?

How much would this save the company in inventory costs compared to the current policy of producing units in each production$$ run?
