NPV$.$ City Hospital, a non$-$profit organization, estimates that it can save $$28,000$ a year in cash operating costs for the next $10$ years if it buys a special$-$purpose eye$-$testing machine at a cost of $$110,000.$ No terminal disposal value is expected. City Hospital's required rate of return is $14\%.$ Assume all cash flows occur at year$-$end except for initial investment amounts.

Calculate the NPV of the special$-$purpose eye$-$testing machine.
