An IE works in the automation department of a surgical equipment manufacturing company that produces specially ordered equipment for hospitals. To upgrade the quality of the assembly process of the camera used in laparoscopic surgery probes, two approaches are available: make and buy. The make alternative has an initial equipment cost of $175,000, a life of 5 years, a $25,000 salvage value, a processing cost of $3,000 per camera, and an M&O cost of $60,000. The buy alternative requires contracting the assembly operation externally at a cost of $8,100 per camera. If the MARR is 12% per year,

how many cameras per year must be assembled to justify the make alternative?
