Provide an appropriate response.You have two investment opportunities. You can invest $6000 at 12% compounded monthly or you can invest $6100 at 12.1% compounded quarterly. Which has the better effective rate of interest? Use a graphing calculator to graph both amounts as a function of time in years. Which is the better investment over twenty years?
What will be an ideal response?
