Hello, let's find the profit maximizing our level of output using the rational rule, at which marginal revenue should be greater or at least equal to the marginal cost.
00:19
So we need to calculate marginal revenue and marginal cost for all possible quantities.
00:28
So here we have different quantities like two, three, 4, 5, 6, 7 and 8.
00:39
And let's find marginal revenues for all of them.
00:44
So it's given that columns 1 and 3 are this demand, this firm's demand schedule.
00:52
So we can find total revenue, multiplying the price in the first column to the quantity in the third column.
01:00
So total revenue from selling two items is 100.
01:09
And similarly we can find other values of total revenue.
01:15
Let me write all of them.
01:32
And now we can find marginal revenue values.
01:35
So the marginal revenue is the additional revenue from producing and selling one more unit...
