So here we're talking about a price.
00:02
We know that wages are 11.
00:04
And we know the productive product is 2 is equal to 5a minus 0 .5 squared.
00:10
So for a, to optimize, what we want to do is, as the question points out, we want to set the price times the marginal product of labor equal to the wage, right? this is my cost.
00:26
This over here is my benefit.
00:29
So the marginal product of labor, dq, dl is equal to 5 minus l.
00:38
So if i substitute in, i get the price of hamburgers, which we were given is 440.
00:47
So we have 4 .4 times 5 minus l is equal to 11.
00:54
Now this very conveniently gives me 22 minus 4 .4l is equal to 11.
01:03
And that gives me 11 is equal to 4 .4l.
01:07
And that when i plug it in the calculator gives me 2 .7 workers...
