Okay, so for this question, let's first say draw the original growth.
00:05
So the original growth, quantity, and price, demand curve, and supply curve.
00:15
So if there's no tax burden, originally the equivalent price is 5, and the equivalent quantity is 10.
00:24
And because of tax burden, that is 50 cents per hamburger.
00:32
So as a result, we will see a supply curve decrease.
00:37
A supply curve, a supply curve shift to the left.
00:40
So it would be the new supply curve.
00:42
And this upper shift, this amount of shift, is actually 50 cents.
00:49
Okay.
00:50
So after the change, the new equilibrium has a price of 5 .2 and has an equilibrium quantity of 9.
01:02
So basically, that's the new equilibrium compared with the original one.
01:06
And you could see that since this is a 50 cents change, and this point is 5 .2, so we definitely know this part, this amount should be 4 .7, right, because it's a 50 cents per shift of it.
01:25
Okay, so that is 4 .4.
01:26
Then we can just mark the consumer surplus, producer surplus, and then we lost after it.
01:33
So the new consumer surplus, because the new price for the consumer is 5 .2.
01:39
So the new consumer surplus should be this triangle here...
