On April 24, 2011, the Beijing News reported an article titled "Why Are Vegetable Wholesale Prices Falling All the Way?" Why did the vegetable farmers commit suicide? "The article immediately attracted the attention of many netizens. When the reporter interviewed the first-level wholesaler Wei Jiliang, he said, "Cabbage has to go through at least three stages from the vegetable farm to the public: the first-level wholesaler, the second-level wholesaler, and the merchants in the vegetable market." Yesterday afternoon At 6 o'clock, in the two vegetable markets of Donghua City, Dongcheng District, the price of cabbage was 1.5 yuan per catty. Why do farmers sell vegetables for 8 cents at a cost of 10 cents, but how come they cost 1.5 yuan in the hands of citizens? The first wholesale market supplies these 2000kg vegetables to the second wholesale market at a 50% cost price increase, and the second wholesale market sells them to the third wholesale market at an additional 65% increase, and finally the third wholesale market sells them to citizens at 1.5 yuan/kg ． If the third wholesale market buys directly from farmers, how much more profit can it make?

2011年4月24日，新京报报道了一篇题为《蔬菜批发价格为何一路下跌？菜农为何自杀？》的文章，立即引起了许多网友的关注．记者在对第一级批发商韦继亮采访时，他说，"卷心菜从菜农地里到市民手里至少要经过3关：第一级批发商、第二级批发商和菜市场商户．"昨日下午6时，东城区东花市的两个菜市场，卷心菜的售价是1.5元一斤．为何成本为1角5的蔬菜，农民却以8分钱的价格出售，到市民手里，怎么成了1.5元呢？第一批发市场把这批2000kg的蔬菜以成本价提高50%供给第二批发市场，第二批发市场又提高65%卖给第三批发市场，最后第三批发市场以1.5元/kg卖给市民．若第三批发市场直接从农民手中购买，则可以多获利多少元？
