关于marginalutility和demandcurve!
1.ThemarketdemandforhotdogisD=50-5P,(P=price,D=quantitydemanded).Whatisthemarginalutilityofthe12thhotdog?
What'sthetotalutilityofthefirst12hotdogs?
2.Whatisthemarginalcostofthe12thhotdogifthesupplyequationisS=1.1*P?
林中伟回答:
1.令D=12解出来的P就是marginalutility
因为他愿意付出的价格等于他的marginalutility
第二题也一样,就是令S=12
totalutility的可以一个一个算出来
当然也可以只算需求曲线跟纵轴和横轴和p=刚才算的mu
这么几条线围成的梯形
