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

I'll help you with the solution. Showing ALL work is your job. Just post the question.

the population after t minutes is 24*3^(t/7)
so, you need to solve
24*3^(t/7) = 100000
3^(t/7) = 12500/3
t/7 log3 = log(12500/3)
