There are 2 regions but they were given by different each other function of demand and supply.
1. 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? Do you know about a good economic web site?
