Shape80 choose the aquarium.

ShapeShape60 choose the science center. 30 choose the planetarium.

Answer 1

1. He surveyed 210 people 2. around 380 3. 38% I'm not sure about the 4th one

Explanation:

For 1 just add up the number(people surveyed)

For 2&3 I did 1000 / 210 you get 4.7619047619 then times that by 80 and you get 380.952380952

Hopefully that helped!
