A net reduction of three employees is expected, with average yearly salaries of $40,000. The system will decrease average yearly inventory by $150,000. Annual operating costs will be $30,000 per year. The expected life of the machine is four years , with an estimated salvage value of zero. the effective tax rate is 40% .
