Given:
The given function is:

Where Y represents the number of bacteria present at time t minutes.
To find:
The time taken by bacteria population to reach 100 bacteria.
Solution:
We have,

Putting
, we get



Divide both sides by 25.

Taking ln on both sides, we get

![[\because \ln e^x=x]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cln%20e%5Ex%3Dx%5D)
Divide both sides by 3.

Therefore, the required time is
minutes.
Well think the answer is x = 14/9 but I don't think there is a full number for this equation.
Answer:
4.99
Step-by-step explanation:
i cant remember how i got 4.99 but can show u how to check
= 55 +<u> 4.99 </u>= 59.99
59.99 divide <u>3</u> = 19.99666667
= 19.99666667 divide 4 (working in reverse as it says 4 times the orig no.)
= 4.99 (was rounded)
