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
這題第二個CS我是把個別的CS加起來=6+3+1+0=10 (0是因為Peter不會買)
所以答案是a? (我沒有答案QQ)
然後第一個求需求量
卡住了…不知道該從哪下手@@
請問該如何做呢？ 謝謝
= = = = =
已解決了，原來就一個人沒買所以需求量是三個 = =
謝謝大家
