5-2. A project your firm is considering for imple- mentation has these estimated costs and revenues: an investment cost of $50,000, maintenance costs that start at $5,000 at end-of-year (EOY) one and increase by $1,000 for each of the next four years, and then remain constant for the following five years; savings of $20,00O per year (EOY110); and finally a resale value of $35,000 at EOY 10. If the project has a 10-year life and the firm's MARR is 10% per year, what is the present worth of the project? Is it a sound investment opportunity? (5.3) 5-27.
