Find the number of the increase:
\n" ); document.write( "\"60-50+=+10\"
\n" ); document.write( "Now divide this by the starting number:
\n" ); document.write( "\"10%2F50+=+0.2\" Now multiply this by 100 to get the percentage of increase.
\n" ); document.write( "\"0.2%2A100+=+20\"%
\n" ); document.write( "
\n" );
