For example, if you pay 20,000 yuan for a hen and only sell an annual package, which opens up 100 small packages, each of which costs 200 yuan per year. The cost per small chicken is thus 0.55 yuan per day. If the hen has 200 days left to live, then the annual package will cost 200 * 0.55 = 110 yuan. How does this work?
