There are basically two ways to go about this:

Explanation:

Take the difference New minus Old, divide this by Old, and multiply by 100 to get the percentage:

#(571320-404729)/404729xx100#

Or:
Use ratio's. Set Sales 2007 to 100%, and get the number for 2008:

#404729/(100%)=571320/(X%)#

Cross-multiply:
#404729xxX%=571320xx100%->#
#X=57132000/404729=141.16%#

which is a #41.16%# increase over the #100%# we started with.
