the 3-day average is 50, so the sum is 3*50 or 150\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "for an average of 48, the sum is 3*48 or 144\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so you have to change the sum by 144-150 or -6
\n" ); document.write( "
\n" );
