The population of a bacteria culture doubles every 3 minutes. Approximately how many minutes will it take for the population to grow from 1,000 to 500,000 bacteria  Choose the correct choice from the following answers:
A) 27
B) 12
C) 14
D) 16
E) 18
This one's easy.   1000 * 2^t = 500,000   2^t = 500   Now gauging, since 2^8 = 256, then 2^9 = 512   So t = 9   But be careful, 't' is in time intervals of 3 minutes   So answer is 9*3=
