The monthly demand curve for playing tennis at a particular club is given by the following equation: P Tennis Match= 9 – 0.20 × Q Tennis Match. The club currently charges members $4.00 to play a match but is considering adding a membership fee. If the club continues to charge the same per play charge the most that it will be able to charge as a membership fee is closest to:
A $40.00.
B $162.50.
C $62.50.
【答案】：C
解析：当每次打台球的价格不变，收取的会员费为消费者剩余部分，即采取一级价格歧视。先写出需求函数：Q=45-5P，P=4时，Q=25；Q=0时，P=9。则消费者剩余对应的三角形面积=1/2*（9-4）*25=62.5
