** POR FAVOR WILL FAN AND MEDAL** Situation: You invest $900 in an account that pays an interest rate of 5.5%, compounded continuously. Calculate the balance of your account after 6 years.
Do you know what compound interest is? Can you tell me a formula we can use here?
I can give a formula.
A=PE\[A=PE ^{rt}\] - A being amount - P being principal - E being mathematical constant - r being intrest - t being time in years
I got 1251.87 is that right?
Not sure, how did you get that answer. Where did you place the numbers?
Never used the equation, so...still trying to understand the equation myself right now.
Are you doing online school?
I am.
Algebra 2 class? That's what I'm on
Algebra 1
IT WAS RIGHT, THANK THE HEAVENS!
I got 29,700 can't be right. Here is how I inserted the numbers. \[A=900*1^{5.5*6}=X\]
It told me I got it right so I guess I did get it right .
Lol, alright. As I was saying I am still trying to figure out how you got it right.
Click equation punch in the numbers and post it. maybe I can get it then.
FV=(900)(2.71828)^(0.055*6)
FV?
\[FV=(900)(2.71828)^{(0.055*6)}\] How did you get 2.71?
The numbers were 900/5.5/6 where did 2.71 come from?
FV=future value PV=present value r= annual rate of interest (in decimal not percent) t=time in years e=constant, 2.71828
Ah
\[FV=(PV)*(e)^{r*t}\]
r*t are in one parenthesis
So, what is the equation on acquiring the constant.
David, you made a slight mistake. The interest is 5.5% but as a decimal, that is 0.055 not 5.5. This means that for ever year the interest is added, the principal increases by a factor of 1.055. $900 over 6 years would be \[$900\times1.055^6=$1240.96\]
