###### Question details

Suppose the inverse demand for coal is estimated to be P = 100 - 0. 15 Q , where P is the price of coal and Q is the quantity demanded. The supply of coal is given by P = 0.1 Q . Graph inverse demand and inverse supply. Calculate and show graphically the price and quantity of coal in a competitive equilibrium in which producers do not consider the future impacts of their actions (i.e., the marginal user cost is external ).
