Question 1153174
A colony of bacteria originally contains 200 bacteria. It doubles in size every 30 minutes. How many hours will it take for the colony to contain 2,000 bacteria?
------------
t = # of 1/2 hour increments.
---
2000 = 200*2^t
2^t = 10
t*log(2) = log(10) = 1
t = 1/log(2) =~ 3.322 half hours.
