How to find the initial and the future population based on today's data?
A certain species of bird was introduced in a certain county 25 years ago. Biologists observe that the population doubles every 10 years, and now the population is 27,000.
(A) - What was the initial size of the bird population? (Round your answer to the nearest whole number.)
n   (initial) = 27 , 000 2 ( 25 / 10 ) [ n ]   (initial) = 4773 - correct.
(B) - Estimate the bird population 8 years from now. (Round your answer to the nearest whole number.)
n   (8 years later) = 4773 × 2 ( 8 / 10 ) [ n ]   (8 years later) = 8310 - wrong.

Step 1
Population is now 27000.
Before 10 yrs,it was 27000/2,
before 20 yrs it was 27000 / 2 2 ,
before 25 yrs it was 27000 / 2 5 2 = 27000 / 4 2 = 4772
Step 2
Population after 8 yrs from now = 27000 × 2 8 10 = 47009
