Question 866914: The number of bacteria N in a culture is modeled by
N = 100 ekt
where t is the time in hours. If N=150 when t=3, what is the time (in hours) required for the original population to double in size ?

Answer by josgarithmetic(39620) (Show Source): You can put this solution on YOUR website!
NOT this, N = 100 ekt,
but THIS: .

You want to first find what is k.

Substituting the given data from the description,

Now you have the model as .

Remember this:
Now, since you want to know t for when N=200, solve for t, ...
