An engineer must recommend one of two machines for integration into an upgraded manufacturing line. She obtains estimates from two salespeople. Salesman A gives her the estimates in future (then-current) dollars, while saleswoman B provides the estimates in today's (constant-value) dollars. The company has a MARR of a real 15% per year, and it expects inflation to be 5% per year. Use PW analysis to determine which machine the engineer should recommend.
