The demand for rice is given by Q d=20-p and the supply is Q s=3p-20.

a. Draw the demand and supply functions. Find the equilibrium quantity and price, and show them on the graph.

b. Suppose due to drought the supply changes to 3p-30. The supply remains the same. Draw the new supply function on the same graph, and find the new equilibrium price and quantity. Has the demand increased or decreased? How did the equilibrium price and quantity change compared to part a.?

The demand for rice is given by Qd-20-p and the supply is Q¹=3p-20.
a. Draw the demand and supply functions. Find the equilibrium quantity and price, and show
them on the graph.
b. Suppose due to drought the supply changes to 3p-30. The supply remains the same. Draw
the new supply function on the same graph, and find the new equilibrium price and
quantity. Has the demand increased or decreased? How did the equilibrium price and
quantity change compared to part a.?
