If a population growing exponentiatIy, doubles in size in 3 years, what is the intrinsic rate of increase (r) of the population?

Explanation

To find the intrinsic rate of increase (r) of a population that doubles in size in 3 years, we can use the formula for exponential growth:

### Step-by-Step Solution:

1. **Understand the Exponential Growth Formula**: The formula for exponential growth is given by:
\[ N_t = N_0 e^{rt} \]
