Question

A scientest is studying a new super bacteria that is threatening to cause an outbreak. On the first day, there were 5 organisms present but on day two the scientest found that each of those organisms had split into 5 more. On the third day, it was discovered that each of the organisms from day two had split into 5 additional organisms. What is the population of bacteria on day 3? A.15 B. 50 C. 125 D. 105

Answer 1

C. 125

Explanation:

Given:

Bacteria on day 1 = 5

On day 2, each bacteria got split into 5.

So, number of bacteria on day 2 =
`5* 5 = 25`

Now, again on day 3, each of the 25 bacteria got split into additional 5 bacteria.

So, number of of bacteria on day 3 =
`25* 5 =125`

Therefore, the population of bacteria on day 3 is 125.
