You are considering making an investment today in an asset that pays you $410 at the end of each month, into perpetuity (ie, forever). The interest rate on the investment is 7.05% p.a. compounded semiannually. The investment has a mandatory wait period of five years before it begins the monthly payment phase. Calculate the amount this investment is worth today. [Hint, the first payment occurs at the end of the first month after the mandatory wait period.) Fi
