\n" ); document.write( "P=-(2)/2+75 [let x=2]
\n" ); document.write( "P=74
\n" ); document.write( ".
\n" ); document.write( "P=-(7)/2+75 [let x=7]
\n" ); document.write( "P=71.5
\n" ); document.write( ".
\n" ); document.write( "P=-(9)/2+75 [let x=9]
\n" ); document.write( "P=70.5
\n" ); document.write( ".
\n" ); document.write( "P=-(11)/2+75 [let x=11]
\n" ); document.write( "P=69.6
