A continuously growing population of bears has a population size of 500 and its intrinsic rate of increase is r = 0.07 per year. Assuming that this rate of increase remains the same, about how long should it take for the population to reach 1,000? (Note: The natural logarithm of 2 is about 0.70.)

Using the formula for exponential growth, the doubling time can be calculated as ln(2)/r. With ln(2) ≈ 0.70 and r = 0.07, the doubling time is 0.70/0.07 = 10 years.
