A high-speed electronic assembly machine was purchased two years ago for $50,000. At the present time, it can be sold for $26,000 and replaced by a newer model
having a purchase price of $37,500; or it can be kept in service for a maximum of one more year. The new assembly machine, if purchased, has a useful life of not
more than two years. If the before-tax MARR is 12%, when should the old assembly machine be replaced? Use the following data table for your analysis.
