From 2003 onward, the number of daily visitors to a website increased by 200% every two years. So, for example, the number of visitors in 2011 was 200% more than the number of visitors in 2009.
In what year was the number of daily visitors 800% more than the number of daily visitors in 2003?
Well this question is very odd if you think about it, since most people would say 2011 because it seems obvious. They would be wrong! This isn't the same as doubleing because you are not doing 200% + 200%, but instead it will be 200% * 400% so the answer to this problem is 2007 using our equation. Could I get confirmation?
