More specifically, figure one illustrates the supply and demand curve for beers. As one can see, each price corresponds to different values for supply and demand, and the market equilibrium is reached at point E, at which the numerical value for supply equals that of demand. In other words, markets use data like these to find prices that will maximize both efficiency and profit while lowering the cost. Also, according to the diagram, one can see that when the price of beer reaches 5£, it exceeds the expected price, and since common people cannot afford such expensive beer, the demand will eventually drop down to zero, as no one will want to buy beer. On the other hand, when prices are down as low as 1£, the demand for beer is so high that supply simply cannot meet demand, and sinks to a value of 0. In conclusion, it can be seen that supply and demand depend on each other, and that a slight change in one value can lead to drastic changes in the other. ~ 如果要谈 Supply 和 Demand,一般都是把 supply 放前面 "supply and demand."~ 没有 allocate efficiency 这种说法的。应该用 "Maximize efficiency" ~·~·~·~·~·~·~·我帮你把句子的顺序改了一下,把语法错误都改了。然后我加了一些新的句子,去掉了一些不需要的句子。最后加了一个小小的 Conclusion. 希望对你有帮助!
