A competitive market has 30 identical firms each with a short-run cost of SC(q) = 3/2q2 + 15q + 150. The market demand for the good is P =105 – 1/5QD. Find the equation for the market supply curve P = S(QS) and use that to find the equilibrium price. Show that this price is a LR equilibrium price. Also find the total consumer surplus in the market. You won’t need an integral for this, just geometry.
