So here we're having a discussion about optimization.
00:03
We know that jeans is equal to three.
00:05
We know that t -shirts is equal to five.
00:08
We know that the price of jeans is equal to 60 and the price of t -shirts is equal to 10.
00:15
We know that the marginal utility of genes is equal to 240.
00:21
And we know that the marginal utility of shirts is equal to 30.
00:27
So is this consumer optimizing? optimization here requires a very specific condition to hold.
00:39
It requires that the marginal utility of genes over the price of genes must be equal to the marginal utility of t -shirts.
00:46
I should call that t.
00:47
I was calling it t over the price of t -shirts.
00:51
The idea being that this term here is equal to utility per dollar.
00:58
Right? if you are going to getting in this case, right, we are getting 30 utility per shirt and each shirt costs 10...
