Suppose the supply curve for apples is given by QS = 2P,
%3D
where QS is the quantity offered for sale when the prices
is P. Also, suppose the demand curve for apples is given
by QD = 182 - 4P I, where QD is the quantity of apples
demanded when the price is P and the level of income is
I.
a) Find the equilibrium P and Q when I = 6.
%3D
b) Find price-elasticity of demand at the equilibrium when
| = 6, and give an interpretation in terms of percents and
classify the elasticity (elastic or inelastic).
c) Find the income-elasticity of demand at the
equilibrium when I = 6, and give an interpretation in terms
of percents. What type of good is this (normal, inferior,
luxury).
