Asked by Micki

So for this question: The number of bacteria present in a culture is given by the following model B=1000e^0.276t; where t= time in minutes. Find the time required to have 6000 bacteria present. Then, round your answer to the nearest tenth of a minute; would my answer be 6.5?
Answered by Steve
Apparently so, since that is what you provide.

My answer is arrived at in this wise:

1000e^0.276t = 6000
e^0.276t = 6
0.276t = ln6
t = ln6/0.276
t = 6.49188

So, 6.5 is the correct answer. Good job.
