\n" ); document.write( ":
\n" ); document.write( "Since it varies inversely, it should be
\n" ); document.write( "\"2.50%2Fx\" = \"100000%2F10000\"
\n" ); document.write( ":
\n" ); document.write( "\"2.50%2Fx\" = 10
\n" ); document.write( ":
\n" ); document.write( "10x = 2.50
\n" ); document.write( "x = .25 for 100000
\n" ); document.write( "
