Allbirds can produce 900 pairs of sneakers per hour at maximum efficiency. There are two 12-hour shifts each day. Due to unavoidable operating interruptions, production averages 500 units per hour.

But demand is unlikely to be affected in the future and will average around 311,000 units each month.Assuming 30 days per month, calculate Allbirds' monthly (1) theoretical capacity, (2) practical capacity, (3) normal capacity utilization, and (4) master-budget capacity utilization
