Question 1121785
.
<pre>
Let x be the number of passengers in 2005.


Then the number of passengers in 2006 was  x*(1+0.08) = 1.08x,


and the number of passengers in 2007 was 1.08x*(1+0.08) = {{{1.08^2*x}}} = 1.1664x.


The increase from 2005 to 2007 was  1.1664x - x = 0.1664x,


and the total percentage of increase was  {{{(0.1664x/x)*100}}} = 16.64%.
