Formula: Bacterial Growth Formula
  
Given: There are 9 cells of a streptococcus lactis colony.
This colony has a double rate of 48 minutes within an optimum medium.
  
Find:  Use the formula above to calculate the time it would take for the given colony to grow to 900000 cells within an optimum medium. Calculate the solution for 't' to the nearest tenth using logarithms.
  
Solution:   t = minutes
