A market has the demand function and supply function as given.
00:05
Determine equilibrium price and equilibrium quantity.
00:08
So, what we're going to do is we're going to set these two functions equal.
00:15
Because at equilibrium, the quantity supply and demand should be equal.
00:22
As should the price.
00:24
So, therefore, we can set both of these equations equal.
00:45
So now, we're going to solve for p.
00:48
So, after we have the price, let's convert it into a decimal.
01:27
So, that is going to be 80 cents.
01:30
So, now we can solve for q.
01:32
So, we can plug in the price into either of these equations.
01:39
Because the quantity supply and demand is the same.
01:49
So, we have 0 .8 times 3 plus 10 gives you 12 .4.
01:58
So, the equilibrium price is 80 cents.
02:05
The equilibrium quantity is 12 .4.
02:14
If the government imposes the price of the market at $6, determine quantity demanded and quantity supplied.
02:24
The shortage or surplus quantity...
