One costs $58,500 and is expected to last 9 years with no salvage value at that time. Costs of use are $30 per crown and 5,000 crowns per year are produced. The other mold apparatus costs $87,500, lasts 9 years, has no salvage value, and is less costly to use at $25 per crown. The dental supplier depreciates assets using MACRS(5).
