You can put this solution on YOUR website!
Percent change is (new - old)/old or (n - o)/o. Think of it as noo!

\n" ); document.write( "From 40 to 60...
\n" ); document.write( "40 is \"old\"
\n" ); document.write( "60 is \"new\"
\n" ); document.write( "So (60 - 40)/40 = 20/40 = 1/2 or 50% change.
\n" ); document.write( "Just be sure to always parenthesize the numerator or you will always accidentally subtract 1 from the new number.
\n" ); document.write( "
