PLEASE HELP ME SOLVE WITH EXPLANATION. THANKS

Wilson Machine Tools, Inc., a manufacturer of fabricated metal products, is considering purchasing a high-tech computer-controlled milling machine at a cost of exist94,000. The cost of installing the machine, preparing the site, wiring, and rearranging other equipment is expected to be exist15,000. This installation cost will be added to the cost of the machine to determine the total cost basis for depreciation. Special jigs and tool dies for the particular product also will be required at a cost of exist10,000. The milling machine is expected to last 10 years, the jigs and dies only five years. Therefore, another set of jigs and dies has to be purchased at the end of five years. The milling machine will have a exist10,000 salvage value at the end of its life, and the special jigs and dies are worth only exist300 as scrap metal at any time in their lives. The machine is classified as a seven-year MACRS property, and the special jigs and dies are classified as a three-year MACRS property. With the new milling machine. Wilson expects additional annual revenue of exist80,000 due to increased production. The additional annual production costs are estimated as follows: materials, exist9,000: labor, exist15,000: energy, exist4, 500: and miscellaneous O & M costs. exist3,000. Wilson's marginal income-tax rate is expected to remain at 35% over the project life of 10 years. All dollar figures represent today's dollars. The firm's market interest rate is 15%, and the expected general inflation rate during the project period is estimated at 2%. Management wants to know if this investment is worthwhile, assuming that the "do-nothing" alternative is feasible but of course generates no additional revenue or costs. Since they are Professional Engineers, they expect that you will conduct a rigorous engineering economic analysis presented using the Case Study Guidelines format. They also expect to see the following analysis conducted: 1. Determination of cash flows in actual (non-in flat ion adjusted) dollars 2. Determination of the rate of return before taxes (no inflation) 3. Determination of the rate of return after taxes (no inflation) 4. Determination of cash flows in inflation adjusted dollars 5. Determination of the rate of return after taxes with inflation 6. A specific recommendation regarding whether or not to invest in the new equipment
