You can put this solution on YOUR website!
Percentage decrease = (new - old) / old times 100% so we get
\n" ); document.write( "% Decr = (1200 - 2500) / 2500 x 100%
\n" ); document.write( "% Decr = -1300 / 2500 x 100%
\n" ); document.write( "% Decrease = -52%
\n" ); document.write( "or a 52% decrease in cost
\n" ); document.write( "
\n" );
