Therefore, of course, we're going to do it.
00:40
We're going to make this extra unit because we're going to get more benefit than cost.
00:48
Let's look at the other condition.
00:50
What happens when marginal cost is greater than marginal revenue? well, if creating an extra unit is going to cost us more than it is going to benefit us, then we don't want to produce a number...
