\n" ); document.write( "Let number of videos to be rented be x
\n" ); document.write( "21+1.5x < 3x
\n" ); document.write( "add -1.5x
\n" ); document.write( "21+1.5x-1.5x<3x-1.5x
\n" ); document.write( "21< 3x-1.5x
\n" ); document.write( "divide by 1.5
\n" ); document.write( "21/1.5\n" ); document.write( "x> 14
\n" ); document.write( "For x > 14 membeship would be a better deal
