Hello, let's look at the question.
00:02
We have been given form's profit function by selling x terms of one commodity the firm gets the price per turn as px and by selling the y terms of another commodity the price per turn is qy.
00:18
The cost of production in selling of x terms of commodity and y terms of second is given by cxy.
00:25
We have to write down the form's profit function.
00:27
Let's write down the form's profit function.
00:46
The necessary condition is x is greater than zero and our y is also greater than zero.
01:03
So we should add to as px is greater than zero, qy is greater than zero, then our cx, x and y is less than zero and cy, x and y is less than zero.
01:27
The first two condition states that the price of two commodity must be positive.
01:31
Third and fourth condition states that the marginal cost of producing these two commodity must be negative, which are these two and of course two are these.
01:39
These condition ensure that firm can increase its profit by producing more of two commodities...
