标题[请益] 消费者剩余
时间Thu Jul 5 19:39:34 2007
题目:Assume that the market demand of good x ,produced by a monopoly
firm A, is x(p)=200-10‧p^(1/2)
(1)Derive the marginal revenue function(MR) for firm A.
(2)Firm A sells good x at 100 per unit. Calculate the consumer's
surplus.
我算出来的MR是:400-8x+3x^2/100
请问第二题的每单位100那是什麽意思? 然後消费者剩余是用积分求出吗?
