As is demonstrated in the following table, two firms, X and Y, have access to five different production processes. Each process has a different cost ($) and gives off a different amount of pollution. Process (daily smoke) Cost to Firm X Cost to Firm Y A (6 tons) 420 715 B (5 tons) 520 845 C (4 tons) 735 1025 D (3 tons) 1180 1300 E (2 tons) 1655 1805 F (1 ton) 2235 2400 G (0 ton) 3005 3095 Both X and Y are located in the same neighborhood. Each ton of smoke that the factories emit causes a damage of $235 to the only resident in the area, Jimmy. Assume the production processes generate the same revenue to the factories and there are no other benefits and costs
