13. (5 points) A customer is considering purchasing an extended warranty today for the brand new car that they plan to purchase today. Because you're an ethical salesman, you encourage the customer to return later and purchase the extended warranty if they don't have enough money to purchase it on today. Your accountant is discouraging you from doing this, saying that it is impossible to sell the extended warranty at a later date because it is attached to the car sold today. Do you agree with the accountant? Why or why not?
