Problem 21-1 Lease or Buy You work for a nuclear research laboratory that is contemplating leasing a diagnostic scanner (leasing is a common practice with expensive, high-tech equipment). The scanner costs $4,700,000 and would be depreciated straight-line to zero over three years. Because of radiation contamination, it will actually be completely valueless in three years. You can lease it for $1,750,000 per year for three years. Assume that the tax rate is 23 percent. You can borrow at 8 percent before taxes. Calculate the NAL. (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) NAL Should you lease or buy? O Buy O Lease
