What Does B^(2t/C) Represent in Bacterial Growth Modeling?

[Niaboc67]

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

Are you sure you copied the equation correctly?
