The population of a bacteria culture doubles every 1 minutes. Approximately how many minutes will it take for the population to grow from 1,000 to 500,000 bacteria	Choices: A) 9 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 1 minutes   So answer is 9*1=
