Firm A currently dumps 243 tons of chemicals into the local river. Firm B currently dumps 126 tons of chemicals into the local river. The government has decided to reduce the pollution and from now on will require a pollution permit for each ton of pollution dumped into the river. The government gives Firm A 61 pollution permits and gives Firm B 65 pollution permits. The abatement costs of one ton of pollution is $113 for Firm A and $165 for Firm B. What would be the total cost of reducing pollution, if the government does NOT allow the firm to trade the permits between each other?
