This is about economic solution.There are 2 regions but they were given by different each other function of demand and supply.1.First question is we won't sell these products on both regions and you can't transport the product each other.So please find the equilibrium price,equilibrium quantity,shortage and surplus of goods on one by one.Functions were written below.

a.Q(demand)=50-0.5P
Q(supply)=-10+P (first region)
b.Q(demand)=120-P
Q(supply)=-20+P (second region)
2.If you can transport the product to these 2 regions cheapestly,please find the equilibrium quantity on these 2regions one by one.If you can't transport any product from first to second region,who can get a profit from them?.Who can't get a profit from these condition?Does anyone know about best economic web site?I really need that.I didn't find it.

To find the equilibrium price, equilibrium quantity, shortage, and surplus of goods in each region, we need to equate the quantity demanded and quantity supplied in each region separately and solve for the price.

1.
a. First Region:
Demand function: Q(demand) = 50 - 0.5P
Supply function: Q(supply) = -10 + P

To find the equilibrium price, we set the quantity demanded equal to the quantity supplied, so:
50 - 0.5P = -10 + P

Solving the above equation for P (price):
1.5P = 60
P = 40

Now, we can substitute the price back into the demand or supply function to find the equilibrium quantity:
Q(demand) = 50 - 0.5P
Q(demand) = 50 - 0.5(40)
Q(demand) = 30

So, in the first region, the equilibrium price is $40, the equilibrium quantity is 30 units, and there is no shortage or surplus of goods since the quantity demanded equals the quantity supplied.

b. Second Region:
Demand function: Q(demand) = 120 - P
Supply function: Q(supply) = -20 + P

Setting the quantity demanded equal to the quantity supplied:
120 - P = -20 + P

Solving for P:
2P = 140
P = 70

Substituting the price back into the demand or supply function:
Q(demand) = 120 - P
Q(demand) = 120 - 70
Q(demand) = 50

In the second region, the equilibrium price is $70, the equilibrium quantity is 50 units, and there is no shortage or surplus as the quantity demanded equals the quantity supplied.

2. Considering transportation between the two regions:
If you are able to transport the products between the regions at a low cost, the equilibrium quantity in each region could change since the products can now flow freely between them.

However, it is not specified how the cost of transportation affects the equilibrium. Without knowing this, it is not possible to determine the new equilibrium quantity for each region.

Regarding the question of who can get a profit and who cannot under the given condition, we would need more information about the costs of production, pricing strategies, and the market conditions in each region.
