It has been estimated that the world demand for wheat can be represented by thefunction P = 80 - 2Q. It has been further found that the countries supplying thismarket have marginal cost curves which when summed together are given by theequation MC = 5 + Q

What price and output levels will prevail in the world market if a free marketsituation exists?

can any one explain that in detail

The sum of the individual MC curves of producers is the supply curve. That is, MC=5+Q=P. Equilibrium occurs when supply=demand. (so, use algebra, solve for Q)

But why "The sum of the individual MC curves of producers is the supply curve"?In monopoly they are lacking of supply curve??
