Sorry about that, I'm talking nonsense. My head is too sore to concentrate.

so using that it would be like above, 6.1 x 109 + 10 / 1.6 x 109

OK, here's a method that is perhaps a bit easier conceptually. You are told that N2000=6.1×109N_{2000}=6.1 \times 10^9

You have worked out the value of kk, and you have either already determined, or can determine by reference to your earlier working, the value of N0N_0.

You can use your values for kk and N0N_0 to find the value of N2010N_{2010}.

Then, from the given value of N2000N_{2000} and the value of N2010N_{2010} you have just worked out, you can determine the % increase in population across the ten year period.
