8. Dell is considering replacing one of its material handling systems. It has an annual O&M cost of $48,000, a remaining operational life of 8 years, and an estimated salvage value of $6,000 at that time. A new system can be purchased for $175,000. It will be worth $50,000 in 8 years, and it will have annual O&M costs of only $17,000 per year due to new technology. If the new system is purchased, the old system will be traded in for $55,000, even though the old system can be sold for only $45,000 on the open market. Leasing a new system will cost $31,000 per year, payable at the beginning of the year, plus operating costs of $15,000 per year payable at the end of the year.

If the new system is leased, the existing material handling system will be sold for its market value of $45,000. Use a planning horizon of 8 years, an annual worth analysis, and MARR of 15% to decide which material handling system to recommend: (i) keep existing, (ii) trade in existing and purchase new, or

(iii) sell existing and lease.

a. Use the cash fl ow approach (insider’s viewpoint approach).
