How to calculate profit, loss, marginal cost in a Perfect Competition

Thankyou so much well explained

Would you sugest a book with problems and graphic like the ones you are resolving to read please. It would really give the source for instance marginall cost, total revenue and on. It would be really appreciated. Than you.

I've spent days watching my lectures and reading books and I was struggling a lot to understand this topic. However in 8 minutes you made it perfectly clear and easy to understand. Thank you so much! This video is exactly what I needed!

Excellent !!

ur vids are shit

Shane from South Africa - date: 13 August 2021. I`ve removed all other channels And kept only Economicsfun. Thank you for helping me so much. I`ve read our textbook, I`ve gone through the study guide & I`ve searched the web for some understanding, NOBODY can explain economics as well as you. thank you very much...

My Prof. makes it sounds like rocket science and psychologically I feel under pressure but this videos are make it so easy to understand.
Your videos are taking the pressure of me! Pls keep continuing what you are doing, it helps A LOT!!!!!!

Thank you so much, easier explanation

Sir,what is opportunity cost?

Thank you for the content. 😴😴😴😴

Thanks for the help! you've been my saving grace, you really are helping the lives of so many people with these. I am thankful for your speed and clarity as well, def helps me understand and grasp it quicker

Hey man, is this for the long run equilibrium? or short run?

this is better than my teacher explanation. THANKYOU

Mrs. Healy's class taught this. Kinda sucks

This video sucks

Need Help. I keep getting a horizontal Marginal cost. Variable cost is always linear ??? Isn't Total variable cost = Variable cost * # of units? How is this ever not linear? Where did I make a mistake?

THANK YOU ... I UNDERSTAND IT MUCH BETTER

Economics has been a tough module for me but lm finding these videos very helpful. all the way from Zimbabwe thank you

Best teacher

Thanks for using precise terms like economic profit instead of just profit, which can be confused with accounting profit. Very well made video.

FANTASTIC, THANK YOU A LOT

Thanks, helpful. Another channel only gave super easy examples but this was more appropriate with thorough explanation.

Great explanation, now i clearly understand all these curves.

how do I do this with a table:
Suppose the following data describe the demand for liquid-diet beverages:

Price $11 $10 $9 $8 $7 $6 $5 $4 $3 $2
Quantity demanded 7 10 13 16 19 22 25 28 31 34


Five identical, perfectly competitive firms are producing these beverages. The cost of producing these beverages at each firm is the following:

Quantity produced 0 1 2 3 4 5 6 7 8 9 10
Total cost $5 $8 $10 $13 $17 $22 $28 $36 $45 $55 $67

(c) How much profit (loss) does each firm make?

Instructions: Enter your response as a whole number. Indicate a negative response with a (-) negative sign.


(d) What happens to price if two more identical firms enter the market?

most helpful ive watched,thankyou me and my son will learn from you.

good shit!

In the long run for perfect competition, total profit is zero

cool!!!

I'm a Economics student at UC Davis and I have to say this video was AWESOME!

very helpful. thankyou!

I watched several of your videos-- Economics/graphs related; it is very easy to follow/understand than anyone could ever explain it to me! Thank you so much for the help!!!

Very helpful stuff! Thank you so much!

This is very helpful, i'm a final year student that never did the commerce subject in high school. Thank you

thanks that was great

Great presentation. Thanks!

this video is soo good... Than you for clearing my doubts.... 

Thank you so much!!!!!!

I'm a bit confused. Shouldn't accounting profit be greater than economic profit since it doesn't include opportunity cost?

I'm not sure how often you add videos but I'm grateful that you do. I've gotten through my economics course because of these lectures. THANK YOU!!!

nice....Thank you.

helped me alot. thank you.

YOU the BEST

in one word, Amazing!!!
