Sheffield Vita produces a wide range of herbal supplements sold nationwide through independent distributors. In response to an increasing demand for its products, the company is considering the purchase of a new packaging machine to replace the seven-year- old machine currently in use. The new machine will cost $170,050, and installation will require an additional $3,150. The machine has a useful life of 10 years and is expected to have a salvage value of $3,905 at that time. The variable cost to operate the new machine is $11.05 per carton compared to the current machine's variable cost of $11.15 per carton, and Sheffield Vita expects to pack 253,000 cartons each year. If the new machine is purchased, Sheffield Vita will avoid a required $10,925 overhaul of the current machine in four years. The current machine has a market value of $12,775.
