A major equipment purchase is being economi­cally evaluated by a team of three design engineers and one production engineer at Raytheon Aero­space. The agreed-upon estimates are P = $560,000, n = 6 years, and S = $100,000. The group disagrees, however, on the estimated annual net savings the equipment will generate. Estimates are summarized below. (a) Use PW analysis and a spreadsheet to identify which estimates, if any, in­dicate that the equipment is economically justified at a MARR of 8% per year. (b) For any estimate(s) indicating that the purchase is not justified, deter­mine the breakeven number of years for the pur­chase to be justified.
