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 $$6,400,000$ and would be depreciated straight$-$line to zero over six years. Because of radiation contamination, it will actually be completely valueless in six years. You can lease it for $$1,320,000$ per year for six years. Assume a $25$ percent tax bracket. You can borrow at $7$ percent before taxes. What is the NAL of the lease from the lessor'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$.,32\mathrm{.}16.)$
