Henredon purchases a high-precision programmable router for shaping furniture components for \($190,000.\) It is expected to last 12 years and have a salvage value of \($5,000.\) It will produce \($45,000\) in net revenue each year during its life. Corporate income taxes are 40 percent, and the after-tax MARR is 10 percent. Develop tables using a spreadsheet to determine the ATCF for each year and the after-tax PW, AW, IRR, and ERR if the router is kept for 12 years.
