Question details
Suppose the supply curve for apples is given by QS = 2P, 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.
b) Find price-elasticity of demand at the equilibrium when I = 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).
d) Find the equilibrium P and Q as a function of I.
e) Find the price elasticity of demand as a function of P and I and determine when this is unitary elastic.
f) Find the income-elasticity in terms of P and I.
