Explain, in words, why your answer is correct.
+23252 Let's say that the original number of visitors is 1000.
An 800% increase is 8.00 x 1000 = 8000, for a total of 9000 visitors.
In what year were there 9000 visitors?
in 2003: 1000.
A 150% increase is 1.50 x 1000 = 1500, for a total of 2500 visitors.
So, in 2005, there were 2500 visitors.
A 150% increase is 1.50 x 2500 = 3750, for a total of 6250 visitors.
So, in 2007, there were 6250 visitors.
A 150% increase is 1.50 x 6250 = 9375, for a total of 15625 visitors.
So, in 2009, there were 15625 visitors.
