Question 868004: Hi,
i was wondering whether you were able to help me rearrange the following formula to find r;
No=150
C=450
N=C/(1+((C-No)/No)*e^-r*t
Thankyou!!
Answer by KMST(5328) (Show Source): You can put this solution on YOUR website!

N=C/(1+((C-No)/No)*e^-r*t has mismatched brackets (3 opening parentheses, and 2 closing parentheses).
I thought that you must have meant N=C/(1+((C-No)/No)*e^-r*t),
showing that the entire 1+((C-No)/No)*e^-r*t expression is in the denominator.

That looks good because if we think of as The relative increase to to get to C from N,

and the equation can be re-written as

Better yet, substituting , we get
