Your neighbor owns a perpetuity of $100 per year that has a discount rate of 6% per year

He offers to sell to you all but the next 20 cash flows (the first to be received one year from today) for $500. In other words, he keeps the first 20 cash flows of his perpetuity and you get all of the rest. Is this a good price for you if the appropriate discount rate is 6%? A) No, because the entire perpetuity is worth only $1,666.67 and your neighbor is taking the best cash flows worth more than $1,200 in present value terms B) Yes, because the present value of the remaining cash flows is $519.68 and you are buying them for only $500. C) No, because the cash flows you receive are only worth $482.16 and that is less than the $500 your neighbor is asking for the cash flows. D) This question cannot be answered.
