I am trying to fugure out if this is a trick question or i got it right. I think the answer is $19,200 (320 x 60). Is that right? Here is the question and the graph. Thanks in advance!

"In the graph below, the solid blue line represents the marginal cost of reducing particle emissions (measured in pounds) for a firm.The dashed line represents a newly imposed pollution charge of$320

for every pound of pollution emitted.

Suppose a firm refuses to reduce its quantity of pollution regardless of any tax imposed. What will be the total tax paid by the firm if the firm chooses to emit60

pounds of particle emissions?"

600 500 400 300 Marginal Cost 200 100 10 20 30 40 50 60 Particle Emissions Reduction (pounds)
