Let \"+x+\" = her 5th score
\n" ); document.write( "[ average of scores ] = [ total of scores] / [ number of games ]
\n" ); document.write( "\"+120+=+%28+115+%2B+84+%2B+123+%2B+101+%2B+x+%29+%2F+5+\"
\n" ); document.write( "\"+600+=+115+%2B+84+%2B+123+%2B+101+%2B+x+\"
\n" ); document.write( "\"+600+=+423+%2B+x+\"
