So let's start by reading the quantities.
00:18
Jews hero equals, um 1000 21 geek wants 1001 c zero.
00:48
He wants five towns hand and see you won equals 5000 on eight, so we can now use this, too.
01:10
Sets off errors to calculate.
01:14
What is the exchange in units on? what is the change in cost? so changing units working on called it deal time q.
01:29
Tilt q.
01:32
It's gonna be kid's hero minus q.
01:38
One.
01:45
That's equal to one, right? and, uh, and that one is just 1000 miners 1001 then deal time seeing or the change in c he's gonna be c zero my nose, c one and it's gonna be 5000 miners.
02:14
5000 and eight on the difference between this tomb is gonna be eight.
02:20
So it doesn't matter if it is negative one or negative eight.
02:25
Cause when we calculated marginal cause i just got here, we're gonna have that is equal to the changing cast over the changing hunt it is that is eight over one which e quarks a.
03:03
So if this two numbers were negative, we will still have a but since we put them now.
03:10
Wait that they're positive and well, we still have eight.
03:15
No...
