Consider the following demand and supply equations for sugar: Q_D=1000-1000P〖 Q〗_S=800-1000P Where P is the price of sugar per pound and Q is thousands of pounds of sugar. a) What are the equilibrium price and quantity for sugar? b) Show graphically the equilibrium price and quantity. Indicate the occurrence of shortage and surplus when disequilibrium arises.
Qd = 1000 - 1000P
Qs = 800 + 1000P
a) Equllibrium price
Qd = Qs
1000 - 1000P = 800 +1000P
200 = 2000P
P = 0.1$
Equllibrium price = 0.1 $
Quantity = 1000 - 1000P = 1000 - 0.1x1000
Quantity = 900
