Calculate the present value of the following cash-flow stream assuming an opportunity cost of capital of 5.25% p.a: T_0 $8449; T_1 $10138.8; T_2 $121828.6. Do your calculations to four decimal places, with two decimal places for your final answer What is the price of a stream of payments of $8449 each that goes on indefinitely with an interest rate of 5.01% p.a? What would be the present value of a yearly annuity of $844.9 for 10 years if the appropriate interest rate is 75% p.a and the first payment starts one year from today
