You need the definition of an average. It is:
\n" ); document.write( "Average of data samples = (sum of data samples) / (number of samples)
\n" ); document.write( "--------------
\n" ); document.write( "Lety the score of the last test = $\"x\"$
\n" ); document.write( " $\"+.92+=+%286%2A.91+%2B+x%29+%2F+7+\"$
\n" ); document.write( " $\"+.92%2A7+=+5.46+%2B+x+\"$
\n" ); document.write( " $\"+x+=+6.44+-+5.46+\"$
\n" ); document.write( " $\"+x+=+.98+\"$
\n" ); document.write( "You need a 98% \n" ); document.write( "

\n" );
