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.

Savings Per Year, $	110,000	140,000	180,000	100,000

(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.
