Eytchison Industrial Products Inc. has developed a new
industrial grinder, model OK-23, that is designed to offer superior
performance to a comparable grinder sold by Eytchison’s main
competitor. The competing grinder sells for $52,000 and needs to be
replaced after 1,000 hours of use. It also requires $9,800 of
preventive maintenance during its useful life. Model OK-23’s
performance capabilities are similar to the competing grinder with
two important exceptions—it needs to be replaced only after 3,000
hours of use and...
