第三題係因為(2)呢個condition入面只係因為價錢升左只會令到quantity supplied升,唔會令supply升

第一同第二題好似會考出過....owning同living呢兩個字有分別...我記得阿sir講過,live唔代表own..所以cost係forgive renting out the house...own既cost就係放棄賣出去既$,而d$可以擺係銀行到收利息,假設無限咁收,同返0個條計無限既公式,就可以得出答案

1. Mr. Chan lives in his own house which is worth $1o million. he can rent out the house at $20000 per month . he can also sell the house and put the money in a bank at an interest rate of 5% per year. wt is the opportunity cost to mr. chan if he intend to live in the house?

a. $10 million
b. $500000 a year
c. $20000 a month
d. there is no opportunity cost because he lives in his own house.
