*Can you explain the result of the calculations as well*

1.You are considering an investment in a mutual fund with a 5% load and expense ratio of 0.25%. You can invest instead in a bank CD paying 2% interest.

a. If you plan to invest for 4 years, what annual rate of return must the fund portfolio earn for you to be better off in the fund than in the CD? Assume annual compounding of returns.

b. What annual rate of return must the fund portfolio earn if you plan to invest for 10 years to be better off in the fund than in the CD?

c. Now suppose that instead of a front-end load the fund assesses a 12b-1 fee of 1.00% per year. What annual rate of return must the fund portfolio earn for you to be better off in the fund than in the CD?
