The engineering supervisor in a company is recommending the purchase of a new machine for a production line. The machine has an initial cost of $310,000 and is expected to be functional for 25 years. At the end of its life, it can be sold for $90,000. The addition of this machine will increase production which results in an increase in annual income of $85,000. The machine will require uniform annual operation and maintenance costs. If the company’s MARR is 21%, how much can be spent on annual operation and maintenance?
