Need with my trade theory homework. i doubt what i wrote was right. consider a monopolistically competitive market for soft drinks in which n symmetric firms face the following demand function: q=s(1/n-b(p-(p with the straight line on which implies the marginal revenue functionmr=p-(q/sb)finally, suppose firms face the total cost functiontc=900,000+100qsuppose the market size, s, is 27,000,000, and the elasticity parameter b is 0.003.diagram the price and the average total cost in the market as a function of the number of firms. what are the equations for each curve, and why does each curve slope up or down? label the equilibrium number of firms and the equilibrium price in the diagram. why is this the equilibrium?
