You can put this solution on YOUR website!
630 = 700 * (100-x) <<--we'll just use x and then work the percentage later.
\n" ); document.write( "630 = 700x
\n" ); document.write( "Divide each side by 700
\n" ); document.write( "90 = x
\n" ); document.write( "The new value is 90% of the previous one. Therefore, they decreased it by (100-90), or 10%.
\n" ); document.write( "
\n" ); document.write( "
\n" );
