The answer above me is correct including their math work!

Answer 2

In the year 2009 there were 3500 birds on an island. If the bird population is declining 2.2% per year it means that in the year 2014 we will have 3500*$(1-0.022^{5})=3500*0.978 x^{5}$= 3131.57 birds. 
The best prediction is that in the year 2014 the bird population will be 3132.
