The Non-Profit University Hospital Is Contemplating Purchasing a New Laboratory

The non-profit University Hospital is contemplating purchasing a new laboratory blood analysis machine at a cost of $1,500,000. Useful life of this machine is 10 years. The hospital currently serves 5,000 patients per year, 40 percent of whom need this machine's analysis as part of the diagnostic tests. The patient's blood samples are presently sent to a private laboratory that charges $150 per sample. In-house variable expenses are estimated to be $85 per sample if the hospital purchases the analysis machine.
