Hi, I'm not really confident with logarhythms yet and I know that there is a way of solving this problem using them. A bacteria divides every 20 minutes, so how many are there after 24 hours? Is this formula relevant here:

colby there is no need for the constant term, it is just t in minutes over 20.

If you have Now you can calculate the constant k: . Divide by and solve for k: And now plug in the time to calculate : And that's a really big number.
Thanks, that was really helpful. And I was able to follow it, which is always a good sign lol
