    Thank you so much! I rather watch your videos than going for 1 and a half hour lecture class because the way you teach is very simple

    I have a question ..
    You are saying that for 1 dollar we can buy 0.5 lbs of fruit but doesnt that affects its MU ? Shouldn't we divide the MU by 2 because we are paying for 1 $ not for 2 $?

      I am confused too, why we can buy a half of the bar of fruits. I think it is unreasonable

      I definitely think that part is a mistake.Very clearly the marginal utility for 1lb of fruit at a price of $2/lb is 60. It cannot double. But that calculation didn't affect anything else in the video.

      If i unserstand ur question correctly, u think that MU/P of 0,5 lb of fruit is 60/2 or 30.
      If so, u might have mistaken, 60 is MU of 1$ worth of fruit, because 1 lb of fruit have price of 2$, 1$ buy you 0.5 lb with MU/P of 120/2 or 60.

      How is your studying coming along. I'm curious. 2017 and I'm feeling the same exact way

    First off....these videos are BAD-A!! Very helpful. Now....the one question/issue I have is: you are saying when use our first $1 it is 1/2 chocolate or 0.5lbs of fruit; then the MU should equal HALF of what it says, right? You said assume that MU is the same for the first half or the whole thing, so shouldn't dollar one go to the first 0.5 lbs of fruit and get 60 MU; then the second $1 would be another 0.5 lbs of fruit, but shouldn't it be zero MU? Or the first should be 30 MU, the second is 30 MU points. I don't understand how we doubled the MU from when a chocolate bar was $1 and then to the example when it was $2.

    Thank you, it's very well explained. I would like to know how you set that MU is 100 for the first product and with how much decreases, from 100 to 80? How do you measure the satisfaction?

    Hey. Why do you say 0.5 lbs of fruit yet you had already calculated the MU per dollar?

    • @aedwards2886
      @aedwards2886 8 років тому +1

      He said that because he was only willing to spend $1 but the entire pound of fruit was $2, so he could have only afforded half of the pound of fruits with the dollar being spent

    What if you get that chocalate for free , what would be the MU/ P ? It has to be undefined because of Number / O equals to undefined. How do we have to express that undefined situation in economics ? -sorry for bad english-
