A project your firm is considering for implementation has these estimated costs and revenues: an investment cost of $50,000; maintenance costs that start at $5,000 at the end of year (EOY) 1 and increase by $1,000 for each of the next 4 years, and then remain constant for the following 5 years; savings of $20,000 per year (EOY 110); and finally a resale value of $35,000 at the EOY 10. If the project has a 10-year life and the firms MARR is 9% per year, what is the present worth of the project? Is it a sound investment opportunity?
