The AMI Company is considering installing a new processing machine for the firms manufacturing facility. The machine costs $220,000 installed, will generate additional revenues of $85,00, and will save $65,000 per year in labor and material costs. The machine will be financed, in part, by a $120,000 bank loans repayable in three equal annual principal installments, plus 9% interest on outstanding balance.

The useful life of the machine is 10 years, after which it will be sold for $20,000. The combined marginal tax rate is 25%.
