Answer 1

Answer:

39900 will be the population at the end of the year 2007

Answer 2

Answer:

39930

Step-by-step explanation:

Initial population =30000

Now population increases by 10% every year.

So after 1 year ( 2005 ) the population =30000+30000*10%= 33000

Now the next year the ( 2006 ) population=33000+33000*10%=36300.

Now population in 2007 =36300+36300*10%=39930
