a monopoly operates in two different markets with the following demands

Q^a = 100-p

Q^5 = 60-p

TC =20Q

b) if the monopoly practices third-degree price discrimination (considering the two market separately) what quantity does it produce in each market? what price does it charge in each market? what are the total profits (combined from both markets)?
