consider a competitive branch made up of 30 firms of two types. tHE 15 FIRMS OF first type are identical with the cost function:C=0.5(Q) q being the production of one of the frims of this type. Firms of the second type are identitcal with the cost function C=1.5(q2)^2 +(q2) + 1.5. q2 being the production of one of he firms we note p the price of the product Determine the overall suppy of the 15 type 1 firms
