$\tt Factory \: packs \: 144 \: ball \: pens \: in \: a \: carton \\ \\ \tt They\:have\:to\:fill\:395\:cartons \\ \\ \tt \therefore No.\:of\:ball\:pens\: required = 395 × 144 \\ \\ \tt \therefore \boxed{\bold{\underline{\green{\tt No.\:of\:ball\:pens\: required = 56880 }}}} \\ \\ \tt They\:already\:have\:57000\:ball\:pens \\ \\ \tt \therefore \boxed{\bold{\underline{\red{\tt They\:do\:not\:need\:to\:make\:ball\:pens}}}}$
