Assume the MARR is 10% per year for this analy­sis. A presently owned machine that was purchased 8 years ago for $450,000 is under consideration for replacement. It has an annual operating cost of $120,000 per year and a salvage value of $40,000 whenever it is replaced. The challenger has a first cost of $670,000, an expected annual operating cost of $94,000, and a salvage value of $60,000 after its 10-year economic life. The breakeven market value of the presently owned machine re­quired to make the AW values of the two machines the same, if the presently owned machine is kept for 5 more years and then replaced with the chal­lenger that has the same AW, is closest to: (choose one)
