No Hayley, you did not have ^3 in your answers

 

after 1 year it would be  8,200x1.03^1  people

after 2 year it would be  8,200x1.03^2  people

after 3 year it would be  8,200x1.03^3  people

 

etc

Also in this one, Hayley got the first part right:

8,200(1.03)^3=8,960 projected population after 3 years.
