You are evaluating two different silicon water milling machine the Techron 1 cost 249000 has 3 year life and has pretax operating cost of 60000 per year. The techron 2 cost 440000 has five year life has pretax operating cost of 40000 per year.for both milling machine use straight line depreciation to zero over the project life a d assume a salvage value 30000 if tax rate is 35% and discount rate is 9 percent compute the eac for Techron 1
