You are evaluating two different silicon wafer milling machines. The Techron I costs $$320,000,$

has a four$-$year life, and has operating costs of $$85,000$ per year. The Techron II costs

$$456,000,$ has a six$-$year life, and has operating costs of $$46,000$ per year. Assume a discount

rate of $10$ percent.

What is Techron I$\text{'}$s EAC?
