如上图所示.需求线与供给线有交点,证明存在均衡点.应为在表中当价格为$1.50时需求的数量为75,而且当价格为1.50供给的数量也为75.这也证明了供求曲线的均衡价格为1.50以及均衡数量为75.
As shown in the above figure,the demand line and supply line has an intersection point.It proves that an equilibrium point is existed.When the price is $1.50 the demand quantity in the table should be 75(litres) and when the price is $1.50 the supply quantity in the table aslo should be 75(litres).This also has proved that the average price of the curve lines of demand and supply is $1.50 and average quantities ware 75(litres).
当价格超过1.50为2.00时供应的数量为120,但是需求的量则为50.因为价格涨的太高使许多人买不起汽油,选择减少汽车的使用或者不买汽油.从而导致供过于求.同理,当价格低于均衡价格为1.00时.需求的量为120供给的数量为50,出现供不应求.所以为了利益的最大化,价格会控制在1.50左右.而价格为1.50时,市场的供给和供求达到均衡出现市场均衡.
When the prices have exceeded $1.50 and is at $2,the supply quantity will be 120(litres) but the demand quantity will only be 50(litres).Because the prices increase that making a lot of people cannot afford to buy petrol(gasline),chhosing to use less of their cars or simply not to buy petrol(gasline) at all,which would lead to over-supplying.Same reason,when the average prices were at $1.00,the demand quantities would be 120(litres) and the supply quantities would 50(litres),which supply shortages occurred.Therefore,In order to maximize the interests of the public.The prices should control at around $1.50.When the prices are at $1.50,the market supplies and demands will be balanced. 如上图所示.需求线与供给线有交点,证明存在均衡点.应为在表中当价格为$1.50时需求的数量为75,而且当价格为1.50供给的数量也为75.这也证明了供求曲线的均衡价格为1.50以及均衡数量为75.
