Kennywood Inc., a manufacturing firm, is able to produce 1,200 pairs of pants per hour, at maximum efficiency. There are three eight-hour shifts each day. Due to unavoidable operating interruptions, production averages 825 units per hour. The plant actually operates only 28 days per month. Based on the current budget, Kennywood estimates that it will be able to sell only 505,000 units due to the entry of a competitor with aggressive marketing capabilities. But the demand is unlikely to be affected in future and will be around 519,000. Assume the month has 30 days. What is the practical capacity for the month?
