Continuous growth help...math people!!! THANKS!?

Ok,



so these two I%26#039;m confused on too...it%26#039;s for a PRE-test so it%26#039;s worth really nothing



29. Rank the following three bank deposit options from best to worst.



-Bank A: 7% compounded daily



-Bank B: 7.1% compounded monthly



-Bank C: 7.05% compunded continuously



LASTLY



28.



Three different investments:



a) Find the balance of each of the investments after the 2 year period.



b) rank them from best to worst in terms of rate of return. (PLEASE EXPLAIN WHY ALSO!!!...thanks!)



-A. $875 deposited at 13.5% per year compounded daily for 2 yrs.



-B. $1000 deposited at 6.7% per year compounded continuously for 2 years.



-C. $1050 deposited @ 4.5% per year compounded monthly for 2 yrs.



Please show all work so that i understand it. Thanks!

Formula for APR is (1 + R/P)^P, continuous is e^R.



R is rate in decimals, and P is the period, assume 360 for daily.



28) $875 =%26gt; 1146.16, $1k =%26gt; 1143.39, $1050 =%26gt; 1148.69



b) A, B, C



29) Clearly it is not A. C would beat A. So it%26#039;s down to C or B



And the APR of B is bettter



A = 7.25, B = 7.34, C = 7.3



So it%26#039;s BCA
