Suppose that the market demand curve for haircuts in some town is
(假设某镇的理发市场需求曲线是)
D=80-2p+5i
where D is quantity demanded per month. P is price per haircut and i is consumer income(in tens of thousands of euros). the supply curve is
(D指每月需求数量,P指每次理发价格,i 指消费者的收入(数以千计的欧元)。供给曲线是:)
S=4P
where S is the quantity supplied per month.
(S指每月供给数量)
Q:Suppose i=3 . Find th equilibrium price and quantity of haircuts?
(问:如果i=3 。找出处于平衡点的价格和数量是多少?)

这不是很简单。。。i=3,equilibrium is where demand equal supply
so, 80-2p+15=4p
6p=95
p=15.83
带入随便哪个式子得到quantity=63.32 取整就是63
顺便说下1楼你这答非所问的。。
