I have the following options: A) I can lease a car for $500 per month with an additional upfront payment of $200. The lease term is for 3 years. Given the terms of this agreement, the implied APR of this payment schedule is 5%. B) Purchase the car today for $23,500. I can sell the equipment at the end of the period for $7,500. Assume the appropriate APR is 5%, and I want to discount on a monthly basis.
