Hi, here we have a supply and demand problem.
00:04
We say that we are given that the supply and demand cares for a certain consumer good are given by these two equations.
00:15
And p is the price in dollars for one unit of this good and q is the number of units.
00:23
A specific tax of $15 of each unit of this good has been proposed and these tax if enacted, will be direct to the suppliers.
00:33
And the question is by how much the equilibrium price increase, will the equilibrium price increase if this tax is enacted.
00:42
First of all, we have to find the equilibrium price without the tax.
00:46
So here we have the supply curve.
00:48
This is we have the demand curve.
00:50
At the equilibrium, the price is at the equilibrium price.
00:55
We are going to have that the two quantities will be equal.
00:58
So these two, the right -hand price.
01:00
Sides here will be equal so we have this equation to solve in terms of p and this is going to give us 8p equals 800 so add the equilibrium without the tax the equilibrium on the equilibrium price without the tax is equal to 100 okay so now we have to find what is the equilibrium price when the tax is enacted...
