please help ive posted this question 3 times now and i keep getting the wrong asnwer from the experts.

You work for a nuclear research laboratory that is contemplating leasing a diagnostic scanner (leasing is a very common practice with expensive, high-tech equipment). The scanner costs $6,200,000 and it would be depreciated straight-line to zero over four years. Because of radiation contamination, it actually will be completely valueless in four years. You can lease it for $1,810,000 per year for four years. The tax rate is 22 percent. You can borrow at 7 percent before taxes. What is the NAL of the lease from the les.ior's viewpoint? (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) Answer is complete but not entirely correct
