Re: calculating interesty' = 0.11y, where y' is the amount you get per year, y is the amount you have, and t is time (in years) Last edited by Ricky (20060107 03:30:49) "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #3 20060107 11:13:48
Re: calculating interestyes its compounded daily. i tried to use the FV=P(1+r)^n equation, but i dont think its right for working it out #5 20060108 12:18:40
Re: calculating interestthanks, i got most of it from playing games. i never did like the stock market much. i have no patience for holding onto the stocks for them long enough to make money lol. #6 20060111 14:28:59
Re: calculating interestI tried to figure it out myself and got 3.432 years using the equation: #7 20060111 16:35:44
Re: calculating interestA=P(1+r/n)^nt #8 20060112 01:24:17
Re: calculating interestThat's how it would be done mathematically, but because Neopets rounds the interest up every day, it would probably end up as being a bit less than that. Why did the vector cross the road? It wanted to be normal.
