Suppose aggregate demand is P(Q) = 21 – 2Q in a competitive environment (the product is an identical/homogenous commodity).There are three firms with different cost structures that could sell:C1(Q) =1 + Q + .5 * Q2C2(Q) = Q + Q2C3(Q) = 100 +Q +  2.5 * Q2What is the equilibrium quantity? Note that demand is different and firms 1 and 3 have a different cost function when compared to prior question.  (Hint: answer is not an integer)
