.
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%5E2%2Ax = 1.1664x.


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


and the total percentage of increase was  %280.1664x%2Fx%29%2A100 = 16.64%.
