After years of overhunting, environmental scientists have reintroduced elk to yellowstone national park. the initial number of elk reintroduced to the park was 230 and, after 8 years, the population is estimated to be about 595. assuming an exponential growth pattern, what is the annual growth rate (rounded to the nearest tenth of a percent) of the elk population in yellowstone national park?

hint: a(t)=ao(1 r)^t a(t) is the final amount, ao is the initial amount, r is the growth rate expressed as a decimal amount, and t is time.

a. 32.3%
b. 1.3%
c. 87.4%
