Given:
Initial number of bacteria = 3000
With a growth constant (k) of 2.8 per hour.
To find:
The number of hours it will take to be 15,000 bacteria.
Solution:
Let P(t) be the number of bacteria after t number of hours.
The exponential growth model (continuously) is:

Where,  is the initial value, k is the growth constant and t is the number of years.
 is the initial value, k is the growth constant and t is the number of years.
Putting  in the above formula, we get
 in the above formula, we get



Taking ln on both sides, we get

Therefore, the number of bacteria will be 15,000 after 0.575 hours.
