人問你你又問返人

第一題係A掛...
我覺得係因為條demand curve 係打直

第一條係D ....
唔係A...

demand curve 打直即係無論price 係咩佢都會consume 一個fixed o既quantity

其實點解我會揀A....

因為我係捻番買煙食呢個case.....

買煙係因為有一個 price inelastic既demand....even price升幾多,都唔會reduce好多QD....

因為煙係一樣addicted既野....

咁捻番呢個case.....佢gamble到spend all income on consumption落gamble度...即係totally addicted...所以我先會捻係Ed=0

如果個答案係D....我捻到既解釋就係因為gambling係唔involve price呢樣野....咁所以就determine唔到條demand curve?

.......

你諗下Ed=0 係咪一定等於spend all the income 先
Ed=0=whatever the price is, you must buy these fixed quantities of goods

Gambling.........我個人認為應該 quantity demanded 唔可以量化....... so, i guess (guess only) is d
