Let \"+x+\" = points she must score in next game
\n" ); document.write( "\"+%28+21+%2B+24+%2B+15+%2B+21+%2B+x+%29+%2F+5+=+20+\"
\n" ); document.write( "\"+%28+81+%2B+x+%29+%2F+5+=+20+\"
\n" ); document.write( "\"+81+%2B+x+=+100+\"
\n" ); document.write( "\"+x+=+100+-+81+\"
\n" ); document.write( "\"+x+=+19+\"
\n" ); document.write( "Beth must score at least 19 to average 20 for 5 games
