Let x be the number of hours
\n" ); document.write( "company A 80 + 55.00 x
\n" ); document.write( "Company B 0 + 75.00 x
\n" ); document.write( "company A < Company B
\n" ); document.write( "75.00 x < 80 + 55.00 x
\n" ); document.write( "75.00 x < 80 + 55.00 x
\n" ); document.write( "-80 < 55 x -75 x
\n" ); document.write( "-80 < -20 x
\n" ); document.write( "4 < x
\n" ); document.write( "x should be greater than 4 hours
\n" ); document.write( " \n" ); document.write( "
