2. Two companies, Gabby Waste Management and Mara Industries both pollute a nearby lake. Each rm dumps 1000 gallons of \"goo\" into Lake Ontario every day. As a consequence, the lake has lost its clarity and the sh are dying. Local residents want to see the lake restored, but Gabby Waste Management production process depends heavily on the ability to dump the goo into the lake. It would cost Gabby Waste $10 per gallon to clean up the goo it generates. Mara Industries can clean up it's goo at a cost of $2 per gallon. (a) If the local government cuts the legal \"goo\" emissions in half for each rm, what are the costs to each rm to comply with the law? What is the total cost to both rms in meeting the goo-emission standard? (2 marks)
