After years of overhunting, environmental scientists have reintroduced lynx to Yellowstone National Park. The initial number of lynx reintroduced to the park was 2,000; after 10 years, the population is estimated to be around 3,750. Assuming an exponential growth pattern, what is the annual growth rate (rounded to the nearest tenth of a percent) of the new lynx 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.)0.65% 

B.)6.5% 

C.)18.8% 

D.)53.3%

3750/2000=1.875

1.875^(1/10) =1.0649 - 1 =.0649 X 100 =6.49%

The answer is B.)
