Its existing machine was purchased $5$ years ago at a price of $$1\mathrm{.}8$ million; six months ago, Cullumber spent $$55,000$ to keep it operational. The existing sewing machine can be sold today for $$242,825.$ The new sewing machine would require a one$-$time, $$85,000$ training cost. Operating costs would decrease by the following amounts for years $1$ to $7$ : Year $1$ $$389,400.$ year $2$ $$399,00.$ year $3$ $$410,800.$ year $4$ $$425,200.$ year $5$ $$433,400.$ year $6$ $$434,500.$ year $7$ $$437,600.$

The new sewing machine would be depreciated according to the declining$-$balance method at a rate of $20\%6.$ The salvage value is expected to be $$379,600.$ This new equipment would require maintenance costs of $$95,600$ at the end of the fifth year. The cost of capital is $9\%$
