Q-1: An investment of $1000 is made at the end of every six months for two years. Suppose the invested money earns 8% compounded semiannually. What is the future value of the annuity using the Algebraic Method? Q-2: An investment of $1000 is made at the end of every six months for two years. Suppose the invested money earns 8% compounded semiannually. What is the future value of the annuity using the Ordinary Simple Annuities Formula? Q-3: Suppose there is an ordinary annuity consisting of four semiannual payments of $1000. Suppose we want to find the present value of the annuity using a discount rate of 8% compounded semiannually. What is the present value of the annuity using the Algebraic Method? Q-4: Suppose there is an ordinary annuity consisting of four semiannual payments of $1000. Suppose we want to find the present value of the annuity using a discount rate of 8% compounded semiannually. What is the present value of the annuity using the Present Value of Ordinary Simple Annuities Formula
