\n" ); document.write( "\n" ); document.write( "let the original salary be \"x\"\r
\n" ); document.write( "\n" ); document.write( "then the new salary is \"x-%28m%2F100%29x=%281-m%2F100%29x\"\r
\n" ); document.write( "\n" ); document.write( "To get back the original amount ,we find what must be multiplied to \"%281-m%2F100%29\" to give \"1\".\r
\n" ); document.write( "\n" ); document.write( "Let the number that will be multiplied to \"%281-m%2F100%29\" to give \"1\" be \"y\", then\r
\n" ); document.write( "\n" ); document.write( "\"%281-m%2F100%29y+=+1\"\r
\n" ); document.write( "\n" ); document.write( "\"y+=+1%2F%281-m%2F100%29+\"\r
\n" ); document.write( "\n" ); document.write( "\"y+=+100%2F%281-m%29\"%\r
\n" ); document.write( "\n" ); document.write( "Therefore, the new salary must be raised by \"100%2F%281-m%29\"% to bring it back to the original amount.\r
