A2/IB Why is MC=MR Profit Maximisation?

A2/IB Why is MC=MR Profit Maximisation? Why in Economics do we consider MC=MR to be profit maximisation?

Weird how we can go to expensive schools and learn from professors and still gain less knowledge in more time than self studying from books and some brilliant Youtube videos. Thanks for the vid!

You teach better than my professor. I learned more in 15 minutes of your videos than hours of lecture

Brilliant, why oh why didn't I search for your video three weeks ago. This video has explained the linchpin concept to a bunch of equations I have been trying to learn. It all makes sense now. Thanks for the help.

[CG-ckrc]

thanks that made me understand it a lot better. All i really needed to know was the difference between current profit and potential total profit. Now i know y

[aarohgokhale]

It is helpful to think of it as maximizing profit as a function of the quantity. To maximize, we would set its derivative with respect to quantity to 0. Well since Profit = TR - TC, its derivative with respect to quantity would be MR - MC. Which means that profit is maximized at MR - MC = 0, which means MR = MC

[zaynab]

But isn’t sales revenue maximized at MR=0, it doesn’t hit the highest point of the TR curve...

[hollym]

Man, that was so very helpful! thank you!

[a.h.t.erangadesilva]

Good job....
thank you very much
You explains well

[KrishnaMittal-qerr]

how did you show that TR is maximum at the intersection point of MR and MC
