i need help please!!!

the NAL

AND question

thank you

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 $5,000,000 and would be depreciated straight-line to zero over four years. Because of radiation contamination, it will actually be completely valueless in four years. You can lease it for $1,450,000 per year for four years. Assume that the tax rate is 21 percent. You can borrow at 8 percent before taxes. What is the NAL? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) Should you lease or buy? Buy Lease
