A culture of bacteria triples every 7 minutes. How long will it take a culture originally consisting of 24 bacteria to grow to a population of 100 000 bacteria? Show ALL work and round to one decimal place, if necessary.

Answer 1

Besides, we saw this one already. You just need to find x such that

24*3^(x/7) = 100000

If you posted the earlier version, with 77 minutes to triple, why did you not just make the fix and redo the calculation as shown? And don't bother to tell us to "show ALL work" ... Just ask your question. We help you find the solution. Following the instructions as required is your job.

Answer 2

A culture of bacteria triples after 7 hours.
What proportion of the original number of bacteria Q0 will be present after 14 hours?
What proportion of the original number of bacteria Q0 will be present after 28 hours?
