A:
The AW values for retaining a presently owned machine for additional years are shown in the table. (Note that the values are the AW amount per each of the n years that the asset is kept.) A challenger has an economic service life of 7 years with an AWC =$-86,000 per year. Assuming future costs remain as estimated for the replacement study, what is the economic service life of the defender, if the company’s MARR is 12% per year? Assume used machines like the one presently owned will always be available.
