A firm trying to decide between public and private warehousing collects some data on the costs associated with each. Alocal public warehouse has told the firm they can store the goods for a monthly charge of $.30 /unit. The firm estimates that if it built the warehouse, it could store the goods for $10/unit plus $50,000 in monthly foxed costs. Assuming these numbers are accurate, what is the smallest volume (in units) that the firm would need to justify bullding a private warehouse, i.e., at what point is 3,000 units 30,000 units 250,000 units 500,000 units 1,000,000 units
