Answer:

  • C. 51.56 million

Step-by-step explanation:

  • Initial number of bacteria = 3.3 million
  • Growth rate = 2.5 times per 10 minutes
  • Time = 30 minutes = 3*10 minutes

Number of bacteria after 30 minutes:

  • 3.3*2.5³ = 51.5625

Correct choice is C

Answer:

after 10 minute total bacteria=2.5×3.3=8.25 millions

in 1 minute total bacteria=2.5×3.3/10 =0.825millions

in 30 minute total bacteria=30×2.5×3.3/10 millions=24.75million is your answer.but i did not get any match.
