Answer:
$800
Explanation:
Price discrimination is a technique used by business owners and business in general that consists on chargin a certain group the maximum they are willing to pay for the product of service, in this case it would be $12 for adults and $8 for students, to know how much they will make we just multiply the cost of the tickets by the tickets bought, and the fmor that withdraw the cost of operation.
[tex]Tickets*Tickets cost=Earnings\\($12*100)+($8*200)=\\(1200)+(1600)=$2800[/tex]
Now we know the museum made $2800 in tickets, we take out the $2000 of the operational cost, and we are left with $800 wich would be the net profit for the museum.
