question
The industry of good X is cost-constant. At first, the market demand function is Q = 1000 - 15P and the industry is at the long run equilibrium, with each firm producing 30 units and the price of X is P = 20. There is an increase in the demand, that is now Q = 1200 - 15P. What is the price of X at the new long run equilibrium?
answer
20
question
