[bluemicrowave64]

when do you know when to use the simple interest formula or the compound interest formula?

[patrickJMT]

@bluemicrowave64 the problem should specifically state that you are earning simple interest or compound interest

Thanks much (this thank you is coming from as far as Jamaica)

[patrickJMT]

happy to help : )

Definitely an excellent problem! Could Log and LN be used here to solve this also? Just a thought.

[patrickJMT]

well, i dont think you would need logs for anything in this problem.

if we are solving for the exponent (maybe we had to figure out how many years would be needed under certain circumstances, for example) then we would need logs

How would I solve this problem: Suppose you invest $200, at a 9% per annum, compounded quarterly. How long will it take your investment to double?

6% is tremendous, where can I get 6%? To be more realistic, with an APR of %1 (Bank of America) You will need to invest $16,707 for 18 years. :-(

hey i have a question, if it is not compounded monthly, but instead semi anually or every 3 month, what should the "n" be? if its monthly , it is 12 but what about other examples? should it be semi anually then n=2?? and every 2 month compounding is n= 4?? thank you so much in advance
