In part 2 we used the same percentages except now we used a 5 year CD instead of a 1 year CD. For 2a we used 10 percent at 5 years and PV of $10,000 to get a future value of $16,105.10 using the FV formula in excel. Then in 2b we changed the rates to 5% and 15% and got the Future values of $12,762.82 and $20,113.57 respectively using once again the FV formula. Then in 2c using the effective rate formula we used the 10% rate and 10 years due to 5 years compounded semiannually and got an effective rate of 10.46% and using the same 10 years and 5% due to it being compounded semiannually we got a future value of $16,288.95. Then is problem 2d we once again found the effective rate using that formula but we used the rate of 10% and 1825 years due to 5 years being compounded yearly giving us an effective rate of 10.52% and using the same 1825 years and .03% and the future value formula we got a FV of $16,486.08.
Then in part 3 we are trying to figure how is the best way to be able bay the $20,000 college bill that will needed to be paid in 5 years. In 3a if we need $20,000 in 5 years at a
