Answer:
15 units
Explanation:
Given:
The demand formula, P = 100 – Q - equation (I)
The marginal revenue formula, MR = 100 – 2Q - equation (II)
Marginal cost, MC = 40 (constant)
There exists a cartel equilibrium; which means MR = MC
Substituting MC = 40 into equation (II), we have
100 – 2Q = 40
2Q = 100 - 40 = 60
Q = 60/2
= 30
Hence, each firm produces 30/2 = 15 units
