Are ya sure katherine?
katherine:
Yes, I'm sure.
zarkam21:
These are exam prep questions so I want to make sure they are correct, could you explain ?
katherine:
\(6000 = 20(e^(2.5t)\) <---- Is the formula
(Which is the population of Bacteria)
\(300 = e(2.5t)\) (How I got 300 is \[6000\div20\]
ln(300) = 2.5t
t = ln(300) / 2.5 = 2.28151299 hours ==> 2 hours

The question asks for a number (Hour) not a word. Don't get those confused.
zarkam21:

katherine:
