Question
Suppose a population of bacteria in a Petri dish has a doubling time of 6 hours. How long will it take for an initial population of 11000 bacteria to reach 20000? Round your answer to two decimal places.

You want t where
2^(t/6) = 20000/11000 = 1.818
t = 6log1.818/log2 = 5.174 hr
Makes sense, since in 6 hrs it will double to 22,000
2^(t/6) = 20000/11000 = 1.818
t = 6log1.818/log2 = 5.174 hr
Makes sense, since in 6 hrs it will double to 22,000
