What will be an ideal response?
A small strip-mining coal company is trying to decide whether it should purchase or lease a new clamshell. If purchased, the “shell” will cost $150,000 and is expected to have a $65,000 salvage value after 6 years. Alternatively, the company can lease a clamshell for only $20,000 per year, but the lease payment will have to be made at the beginning of each year. If the clamshell is purchased, it will be leased to other strip-mining companies whenever possible, an activity that is expected to yield revenues of $12,000 per year. If the company’s MARR is 15% per year, should the clamshell be purchased or leased on the basis of a future worth analysis? Assume the annual M&O cost is the same for both options.
