Answer:
800
Step-by-step explanation:
In order to get the new population of bacteria in 690 minutes, you have to know how often the bacteria will divided in the time frame. So, you have to divide 690 minutes by 230 minutes.
- 690 min. ÷ 230 min. = 3 times
The bacteria will double its colony 3 times in 690 minutes.
- First division: 100 x 2 = 200 bacteria
- Second division: 200 x 2 = 400 bacteria
- Third division: 400 x 2 = 800 bacteria
Therefore, the population of bacteria will be 800 in 690 minutes.
