Logistic Population Model


P(t) = P<<sub>0</sub> * K / P<sub>0</sub> + (K-P<<sub>0</sub>) * E^-RT

P(t) is the population size at time t (measured in days)
P0 is the initial population size
K is the carrying capacity of the environment
r is a constant representing population growth or decay

Problem B-Compute the time for a population to double

Using this model, answer the following question.

B.
How long will it take a population of 13 with a carrying capacity of 80 to double given a r = 0.2? Round your answer to the nearest tenth of a day.
Answer:
Days
