Question 998240: What does B^(2t/C) mean here?
A culture contains 1200 bacteria initially and doubles every 30 minutes. Assuming that the rate of growth is proportional to the number of bacteria, find a function that models the number P(t) of bacteria after t minutes.
P(t) = A e^(kt) = B^(2t/C)
, where

A = 1200
k = 0.0231
B = ?
C = ?
I was able to figure out A and K fine. But where does B and C mean?
Thank you

That expression is not part of the model. It comes from nowhere unless you have clear instructions for it. Your basic model uses P%28t%29=Ae%5E%28kt%29. If you found solutions for k and A, then you have what you need.
