need help with my HOMEWORK question

You work for a nucleat research laboratory that is contemplating leasing a diagnostic scanner (leasing is a common practice with expensive, high-tech equipment). The scanner costs $5,600,000 and 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 $1,650,000 per year for four years. Assume the tax rate is 22 percent. Suppose the entire $5,600,000 purchase price of the scanner is borrowed. The rate on the loan is 8 percent and the loan will be repaid in equal installments. Calculate the amount of the annual loan repayment. (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) Complete the schedules given below and calculate the NAL. (A negative answer should be indicated by a minus sign. Leave no cells blank - be certain to enter " O " wherever required. Do not round intermediate calculations and round your answers to 2 decimal places, e.9., 32.16.)
