My teacher spent about half an hour trying to show us how to do this same problem only using algebra. Thank god for calculus, those who understand it have a much easier time with this stuff.

I've been looking for an explanation like this for hours, thank you so much!

Just discovered this channel and it has helped me so much with my Economics class.

This is a usefull video although it is 10 years past. I really appreciate this. ❤️

Thanks for the cleaning articulating no nonsense video. Please keep making great videos like this.

Never understood what the lecturer taught in class but this video made me understand it better.

oh my lord i could hold on to my microeconomics class only thanks to your lecture. I sincerely appreciate your helps!

Hey, I didn't know Tom Cruise had started teaching microeconomics these days.

I have confused how to calculate price and quantity, now I got it Thanks.

thank you for the video. I was having a hard time figuring out how to do the calculations and your video was very helpful. thank you :)

Exactly what I needed! Thank you!

great explanation but would have proffered if you had given the TC from the onset. caused confusion when i was attempting it

Just started watching today. these videos are awesome!

Bruhh our prof teaches this in pure algebra and it was so long!! After the exam, she taught us this calculus method -.- Nice vid btw

How you got MC=40 and MR = 400-10Q (Given formula couldn't be figured out)

MC=40Q Because at the first of video is 100 + 20^2 Q, son, 100 derivate is zero and 20^2 Q derivate follow the derivate derivate of x^n= nx^n-1, result, 40 Q. On the another hand, 400-10Q also follow derivates rules, derivate of n = 0, and derivate nx= n.

You don't explain how you get a decent amount of the numbers at 3:00. found this very frustrating and not helpful at all.

Can someone explain me how -5q^2/q is equal -10q ?😢

@Syntheti

Жыл бұрын

I’m not sure if you still need help but if you do: Since it was (400-5q)*q That distributes to 400q-5q² When you take the derivative of an exponent, you multiply the the number by the exponent(in this case the number is 5) so 2*5 and then we subtract 1 off the exponent. This is also why 400q becomes 400, another way to write 400q would be 400q¹ and 400q¹⁻¹ is equal to 400*1 So the derivative would be 1*400q ¹⁻¹-2*5q ²⁻¹ which is equal to 400-10q

Thanks this is really helpful!!!

A monopolist has cost function TC = 10 + 2Q, where TC is the total cost of producing Q units of output. Demand in this market is given by theequation Q = 14 - P, where P stands for the price. Calculate the profit that the monopolist will be making. Sir aap solve kar skte ho plz

@kirstyoforiwaa

The profit is 22

What happens when a monopolist invest in the advertisement to shift their demand curve? How to proceed in that case.

Been looking for these kinda vids ! Superduperstuff

Why always in this problems use the inverse demand?

awesome video bro

Gud explain sir ......👍thnx

Very helpful!

Thanks a lot,,it was helpful!

This is not monopoly profit maximizing calculation. Where is AR=P ?

very useful, but can you explain how to charge for the price as well?

dtu attendance here

thank you so much!

great job thanks

Plz explain about TC

it was so helpful

Great thanks!

Thanks ✊

thanks a lot

Sir here how u calculate this MR?

What if it is producing 2 products?

How dtc/dQ =40Q

@EconomicsinManyLessons

TC = 100 + 20Q^2. The derivative of a constant, like 100, is zero. The derivative of 20Q^2 = 2(20)Q^(2-1) = 40Q. See here for more examples: kzread.info/dash/bejne/ZqCOw8GrY7mnj9I.html

How does -5q^2 /q end up -10q??? I've been struggling for hours and theres nothing to explain this.

@EconomicsinManyLessons

Following the rules of differentiation, the derivative of Y = X^a, or dy/dx = aX^(a-1). The derivative of -5q^2 = 2(-5)q^(2-1) = -10q. This may help:kzread.info/dash/bejne/ZqCOw8GrY7mnj9I.html

TC is the total cost of producing the good. It is given in this problem.

Where did the Total cost come from? Was it given or did he work it out?

I basically made them up. I wanted an inverse linear demand of the form P = a - bQ, and I wanted the MC to be an upward sloping straight line.

. Suppose that Intel has a monopoly in the market for computer chips. In order to produce X computer chips, it costs Intel C(X) = 2X2 . If the demand for computer chips is XD = 12 - 1.25 . Find the level of output that maximizes Intel’s profits. What price is Intel charging? Find the marginal cost of producing a computer chip for Intel. What level of output would maximize total surplus in the computer chip market? Suppose the government knew the demand and production functions. Find a price regulation the government could impose that would induce Intel to maximize total surplus, i.e., produce the efficient quantity from part (c). If the government subsidized Intel s for every unit of computer chips produced, what quantity would Intel choose as a function of s? Find the choice of subsidy that maximizes total surplus, i.e., induces Intel to produce the efficient quantity from part (c).

Where did 10Q came from?

The derivative of 5Q^2 is (2)5Q^(2-1) = 10Q. The exponent on Q (the 2) is multiplied by the 5 to get 10, and then you subtract 1 from the exponent to get 10Q.

how do i find profit

@EconomicsinManyLessons

6 жыл бұрын

obaro ogbaide profit = total revenue - total cost. Total revenue = price x quantity. In this problem, total revenue is $360 × 8 = $2880. Total cost is 100 + 20Q^2, and equals 1380 when Q = 8. Profit = 2880 - 1380 = 1500.

Does anyone know how to draw this? I know how to get all the numbers I just don't know how to represent it on a graph.

So... who else thought this was a way to get maximum profit in monopoly...
