Question

For an annual rate of change of -31% find the corresponding growth or decay factor.
I don't have my notes on me so any help is appreciated

Answer 1

I do not know, but my best guess is that you have \[
I = Pr^t
\]And they want you to change it to be: \[
I = Pe^{kt}
\]

Answer 2

\(r = 1-0.31\) in this case, and you have to find \(k\).

Answer 3

Can you solve it?

Answer 4

yeah, thanks :P
