Koch Brothers Purchased a New Production Machine for $200,000

Koch Brothers purchased a new production machine for $200,000. It is capable of producing 400,000 units over its useful life, thus the manufacturer's salesperson claimed the unit cost would only be $0.50. Koch's own engineers recommended that the company acquire a machine that would have a unit cost of production of no more than $0.48 (with a $0.03 variance) . A competitor of the vendor, who also was trying to sell Koch some equipment, claimed that the $0.50 is understated by $0.04 per unit. The total anticipated demand over the asset's useful life is 300,000 units.
