Right, we got a lot of parts here.
00:01
Let's get started right away.
00:03
So basically the shift, the most important thing is you need to see that the demand from this d1, the original here, it went down.
00:14
And it was less of a demand because of some health concern.
00:18
And so that's going to be a key to understanding every single one of these problems.
00:22
What is the leap equilibrium price before the shift? so price, there's a p here for price.
00:28
There's a q here for quantity.
00:30
So the price is b right there.
00:32
You see that where the supply and demand intersect is at b.
00:36
And so the quantity is at e for the equilibrium.
00:41
Very, very, very similar questions for c and d.
00:43
So after this d2 scale, here's our intersection point of supply and demand.
00:48
A is the price, whereas c is the quantity.
00:53
Okay, extracts as express algebraically the difference in quantity demanded at price b before and after the shift.
01:00
So check it out...
