After years of overhunting, environmental scientists have reintroduced mountain goats into Yellowstone National Park. The initial number of mountain goats reintroduced to the park was 1,500; after 11 years, the population is estimated to be around 8,400. Assuming an exponential growth pattern, what is the annual growth rate (rounded to the nearest tenth of a percent) of the new mountain goat population in Yellowstone National Park?
Hint: A(t) = A0(1 + r)^t, where A(t) is the final amount, A0 is the initial amount, r is the growth rate expressed as a decimal, and t is time.
A. 0.17%
B. 1.7%
C. 17.0%
D. 17.9%
