\n" ); document.write( "increasing $\"20\"$ by $\"P\"$ percent: $\"20%2B20%2AP\"$ %
\n" ); document.write( "decreasing $\"60\"$ by $\"P\"$ percent: $\"60-60%2AP\"$ %\r
\n" ); document.write( "\n" ); document.write( "yields the same result:\r
\n" ); document.write( "\n" ); document.write( " $\"20%2B20%2AP\"$ %= $\"60-60%2AP\"$ %
\n" ); document.write( " $\"60P%2B20%2AP\"$ %= $\"60-20\"$
\n" ); document.write( "=> $\"80%2AP\"$ %= $\"40\"$
\n" ); document.write( "=> $\"P%2F100=40%2F80\"$
\n" ); document.write( "=> $\"P%2F100=0.5\"$
\n" ); document.write( "=> $\"P=50\"$
\n" ); document.write( "So, $\"P=50\"$ % of $\"70\"$ is: $\"70%2A%2850%2F100%29=7%2A5=35\"$ \n" ); document.write( "

\n" );
