A manufacturer in Shenzhen, China, is considering whether to make or purchase a key component part. The annual requirement is 50,000 units. One of its suppliers is able to supply the parts for U.S. $15 per unit. The total cost to prepare the purchase agreement with this supplier is U.S. $ 800. However, the manufacturer can produce the parts in-house if it purchases the necessary equipment, which costs U.S. $55,000. Variable cost to produce the item in-house is U.S. $6.50 per piece. Assuming cost is the major decision criterion, use break-even analysis to determine whether the manufacturer should make or buy the item. What is the break-even quantity?
