Suppose a factory emits greenhouse gases from its chimney. Currently, the factory does not abate emissions at all. If it were to abate, its marginal abatement cost curve is MAC = 300 - 2E. The residents of a nearby town are impacted by the pollution and face marginal damages of $3 per unit of emissions. Answer the questions below by filling the blanks. Do not include units in your answers.
1. What is the unabated level of emissions?
2. Find the equation for the marginal damages curve.
