Please try to answer as many questions as you can, I appreciate the help

3. Howell Petroleum is considering a new project that complements its existing business. The machine required for the project costs S3.8 million. The marketing department predicts that sales related to the project will be $2.5 million per year for the next four years, after which the market will cease to exist. The machine will be depreciated down to zero over its four-year economic life using the straight-line method. Cost of goods sold and operating expenses related to the project are predicted to be 25 percent of sales. Howell also needs to add net working capital of $150,000 immediately. The additional net working capital will be recovered in full at the end of the project's life. The corporate tax rate is 35 percent. The required rate of return for Howell is 16 percent. Should Howell proceed with the project? 4. You are evaluating two different silicon wafer milling machines. The Techron I costs $215,000, has a three-year life, and has pretax operating costs of $35,000 per year. The Techron II costs $270,000, has a five-year life, and has pretax operating costs of $44,000 per year. For both milling machines, use straight-line depreciation to zero over the project's life and assume a salvage value of $20,000. If your tax rate is 35 percent and your discount rate is 12 percent, compute the EAC for both machines. Which do you prefer? Why? (Assume that each machine will be replaced (forever) with a new one in the last year of its life.)
