00:01
Okay, so we're going to do from the first question.
00:05
Here you want to find the aggregate marginal willingness to pay.
00:12
So you just need to sum up gio's quantity demanded and john's quantity demanded.
00:17
So price, 6, 5, 4, 3, 2, 1, gio, and then john, 0 ,0, 1, 2, 4, 248, and then 0, 1, 2, 4, 8, and then 0, 1, 2, 3, 4, 5, 5.
00:32
Now you sum up the number horizontally in the by the row.
00:38
You get 0 plus 0 equals 0 plus 1, 1 plus 2 equals 3, 2 plus 2 plus 3 equals 5, 4 plus 4 equals 8, 8 plus 5 equals 13, okay? and so we're just going to graph this quantity.
01:05
0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
01:17
I'm going to extend that, 10, 11, 12, and 13.
01:25
Prices starts from 1, 2, 3, 4, 5, and 6.
01:31
Okay, so when price is 6, the quantity demanded is 0.
01:40
When the price is 5, the quantity demanded is 1.
01:47
When it's 4, it's 3.
01:52
And then when it's 3, it's 5.
01:59
When it's 2, it is 8.
02:05
When it's 1, it's 13.
02:13
Okay, like that.
02:15
This is the aggregate willingness to marginal willingness to pay...
