Q$5.$ A physics lab is considering leasing a diagnostic scanner that costs $$5,800,000,$ and it 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 four years. Assume tax rate is $30\%$ for the

leasing company $($lessor$)$ and zero for the lab. The cost of borrowing is $8\%.$ Over what range of lease

payments will the lease be profitable for both lessee and lessor?
