You are evaluating two different silicon wafer milling machines.

The Techron I costs $$246,000,$ has a three$-$year life, and has pretax

operating costs of $$65,000$ per year. The Techron II costs $$430,000,$

has a five$-$year life, and has pretax operating costs of $$38,000$ per

year. For both milling machines, use straight$-$line depreciation to

zero over the project$$s life and assume a salvage value of $$42,000.$

If your tax rate is $21$ percent and your discount rate is $10$

percent, compute the EAC for both machines.$($A

negative answer$$should be indicated by a minus sign. Do not

round intermediate calculations and round your answers to $2$ decimal

places, e$.$g$.,32\mathrm{.}16.)$
