1 doubt, total revenues keep increasing (with reference to graph), that means the curve which you drew was the marginal revenue curve (@13:23) right?
John Moffat says

No it is not. The curve is the total revenue and the line is the total cost.

Can you explain again why profit maximization is when MR = MC. At 14:40, you said it won’t be worth to drop the price anymore. But the MR=MC point in further down in the graph.
February 21, 2021 at 8:10 am
No it isn’t. When the extra revenue is more than the extra cost we have not reached maximum profit. When the extra revenue is less than the extra cost we have gone past the maximum profit. The maximum profit is when the two are equal.

If MRMC=Loss, why is MR=MC max profit? Shouldn’t it be breakeven point? So no profit and no loss?

Look again at the graph. When MR = MC we are at the highest point on the graph and that is when we are getting maximum profit.

Could you check my final answer for Example 6
Q = 57500
SP = 62.5
Maximum Profit = 3206250
June 29, 2020 at 2:35 pm
It is correct (although all the answers to examples are printed in our free lecture notes!)

Thank you very much. I noticed the answers to examples only after you said. Thank you.

You are welcome 🙂

Thanks for your explanation on why MR = MC at Maximum profit.
I was studying same topic somewhere else where was told to assume MR = MC without any explanation and never could figure out why that was the case.
Thanks again for another brilliant lecture John.

How are you?
I hope you are great.
Thank you for your explanation, I have a question related to the graph which presents the price demand relationship I think we have to plot the price on x-axis and the demand on y-axis because the change in demand is dependent on the change in price this according to my understanding is that right? If wrong so what’s the right and why? Thank you in advance.
April 12, 2020 at 11:31 am
It doesn’t matter which you put on which axis – it is only to illustrate (and you cannot be asked to draw any graphs in the exam).

Thank you sir.

Hello Mr. Moffat, I have a question regarding example 6, where in the answers ‘a’ is said to equal 120. But according to my calculation it is suppose to be 102 since ‘a=100+(0.001*2000)’. This got me confused and would really appreciate your assistance.
Thanks in advance.
March 13, 2020 at 7:32 pm
a = 100 + (0.001 x 20,000)
(not 100 + (0.001 x 2,000) )
March 14, 2020 at 10:35 pm
Thank you for clearing out my confusion. I’d like for you to know that your lectures have been of great help to me.

Can you tell me about the June exam session wether it is going to be conducted in Bangladesh or not?

1) Can we say that as per Example 5 question, we can set the selling price between current $30 to $35 for 1500 unit demand (P=50-0.01 x 1500) that can be got maximum contribution?
2) In the practice, current selling price $30 come from cost plus pricing approach?
April 17, 2019 at 11:38 pm
To be confirmed for my understanding in the Pricing chapter (haven’t go through yet pricing strategics video)
To calculate SP p.u for related demand at max profit, we have to know base information below.
1) current SP p.u which calculated cost plus approach
2) demand (how much we sell in future)
3) Must have experience that our produce is how sensitivity to change in price and demand in the market .

May I ask you one more question, as per example 5 and 6, how do double check that is maximum profit with this selling price?
If I am substitute, 1499 with SP 36, contribution is higher than max contribution at 35 SP.
I do apologize for keeping asking question again.
April 18, 2019 at 5:56 am
1. No. For demand of 1,500, the selling price can only be $35 from the price demand equation.
2. No, you cannot assume that. Where it comes from is of no relevance.
For demand of 1,499, the SP will not be $36 – see the price/demand equation. Highest total contribution is when demand is 1,500 and SP is $35.

Thank you so much sir.

Hello Mr. Moffat,
In the calculation of b in the price equation we must not take into account the signs (plus and minus), is that right? Because if for example the price was 220 and the demand was 5000 and the price drops to 200 and the demand rises to 6000 if we make the calculations by the book we get: -20/1000=-0.02 or 20/-1000=-0.02. And if we put this to the demand equation we will get 200=a-(-0.02×6000).
Could you please clarify on this?
Thank you in advance

is it safe to assume that the MC increases as you carry on producing one more unit because if the Law of diminishing returns?
