200
Five people are hired to give a survey. The first person surveyed 100 people, the second person surveyed twice as many people as the first person, the third person surveyed 50 less people than the second person, the fourth person surveyed 75 people, and the fifth person surveyed 10 more than the fourth person. How many people did they survey all together?
100 + 200 + 150 + 75 + 85 = 610
