Is MARR and money factor the same for a lease.

I have this problem where I have to do a comparison between buying a car and leasing one 10,000 miles/ 36 months .

Perform your analysis for the values of MARR between 1% to 10% (increment of 0.5%), and decide about the best option (keeping the current car, buying a new one, leasing a new one) for each MARR value.

I'm not asking anybody to solve the whole question, just some explanation in terms of the MARR.

Should I see it as the APR for the lease which will be the money factor? or is it something completed different.

Thank you
