We're going to be looking at an important statement here and find the options that will best suit this statement.

When firms in a competitive industry with low barriers to entry are earning positive economic profits, also we are going to be looking at profitability in a perfectly competitive market.
00:23
Let's look at this.
00:25
The first thing that we'll need to do is to draw up the equilibrium for a firm that is earning profits in a perfectly competitive market.
00:39
And we're going to be talking about revenues and costs, and we have the quantities on the horizontal axis.
00:47
So the price at this instant, it should be equal to the average revenue as well as the marginal revenue.
00:55
And we do have the marginal costs and the average total cost curve would cut the marginal cost that is lowest point.
01:10
And so what we can is to illustrate that the profit maximization point is actually where marginal cost is equal to marginal revenue.
01:21
So that's at this point.
01:22
And at this point, the average costs are lower than the price or the average revenue curve.
01:32
And therefore, the shared area represents the profit...
