In a market for dry cleaning, the inverse market demand function is given by P = 100 - Q and the (private) marginal cost of production for the aggregation of all dry-cleaning firms is given by MC=10+Q. Finally, the pollution generated by the dry cleaning process creates external damages given by the marginal external cost curve MEC = Q.
