Hello, can you please solve this microeconomic question. Thanks in advance!

Suppose the government thinks that consumers today are eating too much red meat. Let the government impose a $50 per hundredweight specific tax on the monopolist to reduce cattle production and consumption. Let the inverse demand for cattle be P=1000-20Q and the new total cost to produce a cow be TC=1000+5Q2. What is the change in producer surplus from implementing the tax relative to the monopoly equilibrium? O -2,780 O -1,805 O -975
