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? Explain, in words, why your answer is correct.

Note something, Choff

 

A 100%  increase means that something doubles  =  (1 + 1) =  2 times as much

A 200% increase means that  something triples = (2 + 1)   = 3 times as  much

So  an 800%  increase   means that sometning is  (8+1)  =    9 times as  much as  the  original amt

 

2003  = A   = the original number

2005  =  3A  =   200% increase  over  2003  = 3 times as  many

2007  =   3 (3A) =   9A  =   800% increase over 2003  = 9 times as  many
