In a bacteria growing experiment, a biologists observes that the number of bacteria in a certain culture triples every 2 hours. After 8 hours, it is estimated that there are 2 million bacteria in the culture. What was the original population of the bacteria?

We were also told that the population triples after every 2 hours. Which means that the original amount is multiplied by 3 after every 2 hours. Example if the population was 1000 at 1 pm, at 3 pm, the population will be 1000×3 = 3000.

So next, let us find how many two hours are there in 8 hours:

8 = 2+2+2+2

hence there are 4 two hours in 8, so we can conclude that after 8 hours, the population has tripled 4 times. which are at 2 hours, 4 hours, 6 hours and 8 hours. So working backwards from 8 hours, we have;

2,000,000 (after 8 hours)

2,000,000 ÷ 3 = 666,666.67 (after 6 hours)

666,666.67 ÷ 3 = 222,222.22 (after 4 hours)

222,222.22 ÷ 3 = 74,074.07 (at 2 hours)

74,074.07 ÷ 3 = 24,691.35

hence the original population at 0 hours = 24, 691 bacteria

The original population of the bacteria is approximately 24,691 bacteria.

What are bacteria and how do they multiply ?

Bacteria is the most freely living organism and has one biological cell. They have a large variety of prokaryotic microorganisms and are the first forms of life on earth. Bacteria have the ability to multiply

As per the text after 8 hours of duration, the bacteria have doubled to 2 million in culture.

At 8 hours the bacterial population was 2 million. after that

2,000,000 ÷ 3 = 666,666.67 (after 6 hours)

666,666.67 ÷ 3 = 222,222.22 (after 4 hours)

222,222.22 ÷ 3 = 74,074.07 (at 2 hours)

74,074.07 ÷ 3 = 24,691.35

This shows the bacteria multiplying rate.
