John supervises an aging production line that constantly needs maintenance and new parts. Last month he spent $$24,000$ replacing a failed controller. The net installed cost of the new line to replace the old line is $$589,000$ with a useful life of $10$ years. In the first year its operating cost will be $$120,000,$ and it will generate annual revenues of $$319,000.$ Each year the operating cost will increase by $$8,000$ and the revenues will fall by $$12,000.$ After $10$ years the equipment will have a value of $$109,000$ in the next re$-$building of the line. Assuming the interest rate is $11\mathrm{.}3\%,$ calculate the Net Present Worth.
