After a devastating winter, where thousands of fish died, an environmental scientist has replenished the trout stock in a fishing pond. He started with 5,000 baby trout and has finished a count to find that in 8 years the population is now estimated to be 33,000. Assuming an exponential growth pattern, what is the annual growth rate (rounded to the nearest tenth of a percent) of the new trout fish population? Hint: A(t) = Ao(1 + r), where A(t) is the final amount, Ao is the initial amount, r is the growth rate expressed as a decimal, and t is the time.
