Hello, this problem gives us a table showing marginal revenue and marginal cost.
00:11
We are accustomed to showing marginal revenue as derivative of the revenue function and marginal cost function.
00:29
The profit function, once again, is the difference between the revenue of producing, selling q items minus the cost of producing q items and the marginal profit marginal profit at q is equal to the marginal revenue at q minus the marginal cost at q or using these annotations marginal revenue minus okay what do these numbers mean here the marginal revenue at 5 ,000 we are told in part a to take q equals 5 ,000 and decide whether we should increase, whether we should increase production or decrease 5 ,000.
01:39
What do we have at the q level of 5 ,000? we have the marginal revenue.
01:52
It's the marginal revenue of 5 ,000.
01:57
Which is positive, pardon me, doesn't matter here, and the marginal cost at 5 ,000 is 48.
02:09
This means that the marginal profit at 5 ,000 is 60 minus 48.
02:24
What does this number here represent in terms of marginal profit? it means that, it means that.
02:39
The marginal profit of 5 ,000 equals so, it means that producing one more, item the profit will increase by $12.
03:06
So the question was, so this 12 here means that an increase of $12 new items produced, this is when the production level is already at 5...
