Suppose you need to decide whether to keep a machine or replace it with a new one: Old machine: Old machine can operate for 6 years with operating cost of $120,000 per year. New machine: Replacing old machine with new one requires capital cost of $300,000 in year zero (zero salvage value for old machine). Capital cost is depreciable from year 1 to year 6 (over six years) based on MACRS 5-year life depreciation with the half year convention (table A-1 at IRS). New machine can produce with lower operating cost of $40,000 per year for 6 years (from year 1 to year 6). Assume both machines produce similar good with similar value that yields similar revenue. Consider income tax of 35% and minimum rate of return 10%. Construct incremental analysis and conclude which alternative is more economically satisfactory? Please show your work.
