The maintenance of a machine in a manufacturing plant currently costs a company $8,000 every year (paid at the end of each year) with the cost increasing by $1,000 each subsequent year. Because of this, the plant manager is considering replacing this machine with a newer one which would cost $20,000 to purchase today, and then $4,000/year increasing by $300 in each year to maintain (also paid at the end of the year). If the company's MARR is at 8% per year compounded annually, what would be the discounted payback period (in years) for this proposed investment? tn67
