A granary has two options for a conveyor used in the manufacture of grain for transporting, filling, or emptying. One conveyor can be purchased and installed for $90,000 with $2,500 salvage value after 16 years. The other can be purchased and installed for $130,000 with $5,500 salvage value after 16 years. Operation and maintenance for each is expected to be $14,000 and $15,000 per year, respectively. The granary uses MACRS-GDS depreciation, has a marginal tax rate of 25%, and has a MARR of 9% after taxes.
