A company that makes door knobs has found that the demand for its base model is fairly constant at the rate of 60,000 units per year. Each model of door knob is made using the same equipment, and it costs $120 in lost production and scrap every time that a change is made from producing one model of door knob to another. The cost of materials and labor in each door knob is $10, and the inventory holding cost is 35% of the per- unit cost per year. If the base model door knobs are produced at the rate of 800 per day, how many should be produced in each production run based on 300 working days per year?
