4. (20 points) Macon Company is considering a new assembly line to replace the existing assembly line. The existing assembly line was installed 3 years ago at a cost of $90,000; it was being depreciated under the straight-line method. The existing assembly line is expected to have a usable life of 6 more years. The new assembly line costs $120,000; requires $9,000 in installation costs and $5,000 in training fees; it has a 6-year usable life and would be depreciated under the straight-line method. The new assembly line will increase output and thereby raises sales by $10,000 per year and will reduce production expenses by $5,000 per year. The existing assembly line can currently be sold for $15,000. To support the increased business resulting from installation of the new assembly line, accounts payable would increase by $5,000 and accounts receivable by $10,000. At the end of 6 years, the existing assembly line is expected to have a market value of $4,000; the new assembly line would be sold to net $15,000 before taxes. Finally, to install the new assembly line, the firm would have to borrow $80,000 at 10% interest from its local bank, resulting in additional interest payments of $8,000 per year. The firm pays 20% taxes and its shareholders require 10% return.
