![**Long Run Equilibrium**
Consider a perfectly competitive market with \( n \) identical firms. The cost functions of an individual firm are:
\[
TC = q^3 - 4q^2 + 74q
\]
\[
MC = 3q^2 - 8q + 74
\]
The market demand is given by:
\[
P = 120 - Q
\]
#### Instructions:
a) Graph two representations: one for the market and one for an individual firm to demonstrate the long-run equilibrium.
b) Determine the output per firm in the long run, \( q = \ldots \), ensuring the firm operates at its minimum cost.
c) Establish the long-run equilibrium price, \( P = \ldots \), with justification.
d) Calculate the total market quantity purchased, \( Q = \ldots \), with reasoning.
e) Assess the number of firms that can exist in equilibrium, \( n = \ldots \) firms.
f) Explain why no additional market entry occurs.
g) Clearly label all equilibrium values on your graph.
