a$.$ Using FTRN$\text{'}$s disclosure of future minimum operating lease payments, estimate your own present value using the provided discount rate. For the "thereafter" portion, assume that future lease payments continues after $2028$ at the $2028$ amount until exhausted $($so you should end up with more than five and less than ten total years, with the final year serving as a "plug" number to ensure you hit the same "total minimum lease payments" figure$).$

b$.$ Given that you used the same discount rate that the company discloses it uses, what is the most likely explanation for the difference between your calculation and the company's reported number of $$3,487?$
