Your videos are helpful but the audio/video quality is so laggy that it makes it impossible to watch. Can you please fix your render settings and maybe reupload?

[@nhatphungblancharddelabrosse]

I have but it keeps on lagging every now and then. I think your videos could be as helpful as Khan Academy if the quality was equivalent.

On most of these I need a tutorial to explain how we go about getting the answer...

[@angusho5871]

Thanks for your video! it helps me a lots But I have a question at 34:53 Why TC is equal to 100Q+10Q^2 ? I just can't figure it out

[@angusho5871]

Economics Course Oh, I got it :))

[@ninadshah2071]

@@economicscourse i still couldn't figure it out.... Can you please make me understand this? How did MC become TC by multiplying with Q? by the way your videos help a lot thank you!

[@ninadshah2071]

@@economicscourse thank you so much for replying to me! Now i got it and your videos help me so much thank you!

@@economicscourse Wouldn't TC be the integral of MC tho? And then TC 100Q+5Q^2...

[@espanolparati3080]

@@jiayiwu1122 It could be just in the case we are assuming no Fixed Costs.

Thanks brother

In question 10-d. Specifically in the case iii, the directors wage would be equal 150 dolars per unit solde. Wouldn't this alter the marginal cost of selling an extra unit by $150? In this case MC = 100 + 10Q + 150 -> MC = 250 + 10Q. This would change the monopoly price and quantity and hence alter the DWL. Thoughts?

[@helwesh.700]

The total cost is equal to 100+5q^2, not 100+10q^2

[@helwesh.700]

​@@economicscourse Exactly! I forgot "q" on my first comment, but what I was going to write is that "100q + 5q^2" is correct. Do you got it? The derivative: 100+ 10q (Cmg)
