Data from problem 65

Bailey, Inc., is considering buying a new gang punch that would allow them to produce circuit boards more efficiently. The punch has a first cost of \($100\),000 and a useful life of 15 years. At the end of its useful life, the punch has no salvage value. Labor costs would increase \($2\),000 per year using the gang punch, but raw material costs would decrease \($12\),000 per year. MARR is 5 percent/year.
