Suppose that each firm in a competitive industry has the following costs:
Total Cost: TC = 50+ 1/2q²
Marginal Cost: MC = q
where 9 is an individual firm's quantity produced.
The market demand curve for this product is:
Demand D = 160 - 4P
where P is the price and is the total quantity of the good.
Each firm's fixed cost is $
