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$$ company's best$-$selling refrigerator. The annual demand for this has been about $7,500$ units each$$ year, and this demand has been constant throughout the year. The production capacity is $210$ units per day. Each time production$$ starts, it costs the company $$$$120$ to move materials into$$ place, reset the assembly$$ line, and clean the equipment. The holding cost of a refrigerator is $$$$46$ 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.
