Whitfield Corp. has just installed a new machine. The machine cost \$47,000. Its annual operating costs are \$28,000, exclusive of depreciation. The machine will have an 8-year life with a residual value of zero. One month after the purchase of this machine, a different company offered a new machine that will reduce the annual operating costs to \$16,000, exclusive of depreciation. The new machine has a cost of \$72,000.
The "old" machine can be sold outright for \$24,000. The new machine has an 8-year useful life and a salvage value of \$4,000. Cash sales will be \$220,000, and other cash expenses will be \$140,000 for each of the next eight years, regardless of this decision.
Calculate net present values (in $) of each alternative using a 12% desired rate of return, and determine what should be done.
