A portable concrete test instrument used in construction for evaluating and profiling concrete surfaces (MACRS-GDS 5-year property class) is under consideration by a construction firm for $ 26,000. The instrument will be used for 6 years and be worth $ 1,500 at that time. The annual cost of use and maintenance will be $ 6,500. Alternatively, a more automated instrument (same property class) available from the manufacturer costs $ 32,000, with use and maintenance costs of only $ 9,000 and salvage value after 6 years of $ 2,000. The marginal tax rate is 25%, and MARR is an after-tax 12%. Determine which alternative is less costly, based upon comparison of after-tax annual worth.
