Suppose that a savings account pays an effective rate of interest of 8.2 percent. What is the equivalent annual compound interest rate if interest is compounded semiannually? Answer = percent. Complete the table below giving the amount P that must be invested at interest rate 10 % compounded quarterly to obtain a balance of A = $180000 in t years. Two investments are made at the same time. The first consists of investing 1790 dollars at an annual rate of interest of 10.4 percent, compounded semiannually. The second consists of investing 1600 dollars at an annual rate of interest of 10.4 percent, compounded daily. How long will it take for the two investments to be worth exactly the same amount? (Assume compound interest at all times.) Answer = | years. (Be sure to give several decimal places of accuracy!)
