Final answer:
Berkshire Inc. uses a periodic inventory system, which involves regularly scheduled physical counts of inventory to determine the quantity on hand.
Step-by-step explanation:
Under the periodic inventory system, Berkshire Inc. regularly schedules physical counts of inventory instead of continuously tracking inventory levels in real-time or making immediate adjustments for each sale. This means that the company physically counts its inventory at set intervals, such as monthly or annually, to determine the quantity on hand.
