You are the CFO for an airline and are deciding whether you should lease some new airplanes. Assume you may buy them at $$100MM$ or to lease over $10$ years at $$12\mathrm{.}5MM$ aftertax $($payments in arrears$).$ You believe the residual value will be $$20$ MM after $10$ years and have an after$-$tax interest rate of $5\%.$ What is your Net Advantage of Leasing $($NAL$)?$

Make sure you do not add any dollar signs or commas to your answer. Just put in the whole number of dollars $($no need for cents here$).$
