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 $$5,600,000$ and it would be depreciated straight$-$line to zero over four years. Because of radiation contamination, it actually will be completely valueless in four years. You can lease it for $$1,640,000$ per year for four years. The tax rate is $21$ percent. 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$.,32\mathrm{.}16.)$
