Calculate the financial impact of buying a CT unit that would cost $3.0 million, would have a five-year useful life, would have a 10 percent salvage value, would have a profit per procedure of $400, and would generate an estimated volume of 450 procedures per year.

Our long-term debt represents the remaining balance on a 30 year loan taken out in 1996 at 7% with options to refinance every 10 years. If we refinance for the remaining 10 years at 3%, how much interest expense will we save over the remainder of the loan
