Puffy · Answer 1

Answer: 7,864,320

Step-by-step explanation:

Because the doubling time is 20 minutes, the bacteria would have gone through binary fission (cell division in bacteria) 18 times after 6hours (6*60/20)

Nt=N0 * 2^n

N0=starting population

n=number of times bacteria divide

So

30*2^18=7,864,320
