Part III. Show your solutions in this part 1.) Harold's Inc. is trying to determine whether its current assembly system needs to be replaced with a more efficient one. The new system would cost $85,000 and it would have an estimated economic life of 10 years, after this period, it would have an economic value of $ 7,500. The yearly operation expenses are $30,000 per year and that Declining Balance Method of depreciation will be employed. Use salvage value = $ 6,000. With a remaining useful life of 5 years, the current BV of the present system is at $13,500 and has a present realizable MV of $9,000. Determine the most economical period to keep the current system before replacing it by performing an after-tax analysis. Use after-tax MARR = 18% per year and effective tax rate = 35%. Use table below for additional information. Year End of year MV $ 7,500 End of year BV $ 9,000 Operating Expense $ 40,000 1 2 $ 6,000 $ 7,000 $ 50,000 3 $ 5,800 $ 6,000 $ 60,000 4 $ 4,200 $ 5,500 $ 70,000 5 $ 3,200 $ 4,500 $ 80,000 Part III.
