An airline is trying to decide whether to lease a new a be Boering $737$ Max. that costs $$135\mathrm{.}0$ million. Pertinent information:

$$ Cost of aircraft: $$135\mathrm{.}0$million

$$ Lease cost: $$18\mathrm{.}0$million per yr $($at beginning of each year$)$

$$ No salvage value

$$ Cost of debt $7\mathrm{.}14\%$

$$ CCA rate for aircraft: $25\%$

$$ Tax rate: $30\%$

Should the airline buy or lease the Boeing $737$ Max?
