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 $$6,800,000,$ Because of radiation contamination, it will actually be completely valueless in four years. You can lease it for $$1,950,000$ per year for four years. Assume that the tax rate is $25$ percent. You can borrow at $7$ percent before taxes. Assume that the scanner will be depreciated as three$-$year property under the MACRS depreciation. What is the NAL of the lease? $($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$.,32\mathrm{.}16.)$
