Q:
Four people each have a different willingness to pay for one unit
of a good: George will pay $15, Glen will pay $12, Tom will pay $10
, and peter will pay $8. If price is equal to $9 per unit
then the quantity demanded in the market will be ____
and the consumer surplus for this unit will be _____
a. 3; $10
b. 3; $37
c. 3; $36
d. 4; $8
这题第二个CS我是把个别的CS加起来=6+3+1+0=10 (0是因为Peter不会买)
所以答案是a? (我没有答案QQ)
然后第一个求需求量
卡住了…不知道该从哪下手@@
请问该如何做呢？ 谢谢
= = = = =
已解决了，原来就一个人没买所以需求量是三个 = =
谢谢大家
