The equation is:\r
\n" ); document.write( "\n" ); document.write( "t = s/100 * 5 + 2 \r
\n" ); document.write( "\n" ); document.write( "for example: 600/100 * 5 + 2 = t
\n" ); document.write( " 6 * 5 + 2 = t
\n" ); document.write( " 30 + 2 = t
\n" ); document.write( " 32 = t\r
\n" ); document.write( "\n" ); document.write( " 1000/100 * 5 + 2 = t
\n" ); document.write( " 10 * 5 + 2 = t
\n" ); document.write( " 50 + 2 = t
\n" ); document.write( " 52 = t \n" ); document.write( "

\n" );
