2 (15 pts) Alpha Semiconductor Co. is evaluating whether to add another IC production line. The line would cost $80000 and would have no market value at the end of its 7 year life. The facility would be depreciated using straight line depreciation. Gross income (GI) and annual operating costs (AOC) are expected to be $20000 and $6400 in year 1, respectively. GI and AOC are expected to increase by $800 per year for the next 6 years. The company's effective tax rate is 40% and it uses an after-tax MARR of 15%. After 7 years, the line is actually sold for $40000. Is it worthwhile to invest?
