You are evaluating two different silicon wafer milling machines. The Techron I costs

$$237,000,$ has a three$-$year life, and has pretax operating costs of $$62,000$ per year. The

Techron II costs $$415,000,$ has a five$-$year life, and has pretax operating costs of $$35,000$

per year. For both milling machines, use straight$-$line depreciation to zero over the

project's life and assume a salvage value of $$39,000.$ If your tax rate is $21$ percent and

your discount rate is $8$ percent, compute the EAC for both machines. $($Your answer

should be a negative value and indicated by a minus sign. Do not round intermediate

calculations and round your answers to $2$ decimal places, e$.$g$.,3216.)$

Which machine should you choose?

Techron $1$

Techron II
