Let x represent the sum of his scores. So when he divides the sum by 6 he gets:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x%2F6=84\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"cross%286%29x%2Fcross%286%29=6%2A84\" Now multiply both sides by 6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x=504\" Multiply\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the sum of his scores is 504. Now divide 504 by 7 to find the correct average:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"Average=504%2F7=72\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the correct average is 72
\n" ); document.write( "
\n" );
