Question
Suppose there are three types of Apples A, B and C
being sold and consumed. The demand and supply equations
for each type are:
D, = 20 – 2P, + 4P, + Pc S, = 4P,-5
D = 10 + 3P, - 5P, + 2P. S,= 3P, - 7
De = 70+ 4P, + 2 P, - 5P. Sc = 5P. – 16
• Determine equilibrium prices and quantities using
Cramer's rule.
• Calculate the elasticity of demand for B with respect to
prices of variety A, B and C and interpret the economic
meaning of the results.
