Given this paragraph, show me how to calculate how many total patrons can be served by all of the Schauspielhaus theaters?

1430 total patrons can be served. There are 750 seats in Schauspielhaus Zürich, 400 in the Schiffbau/Halle, 200 in the Schiffbau/Box and 80 in the Schiffbau/Matchbox. This totals to 750 + 400 + 200 + 80 = 1430 seats. Each patron requires one seat
