In a particular region of a national park, there are currently 330 deer, and the population is growing. The equation that best models the deer population growth at this park is LaTeX: A=Pe^{rt}A = P e r t, where "A" is the amount of deer in the park after "t" years if the initial population "P" increased at a rate of "r". If it takes 6 years and 7 months for the deer population to double, what is the annual rate of increase? Give your answer as a percent rounded to the nearest tenths place.
