Answer:
The total number of people at the movie theatre is 700.
Step-by-step explanation:
Formula
[tex]Percentage = \frac{Part\ value\times 100}{Total\ value}[/tex]
As given
At the movie theatre 30% of the audience members were children.
If the number of children at the movie theatre was 210.
Percentage = 30%
Part value = 210
Put in the formula
[tex]30 = \frac{210\times 100}{Total\ value}[/tex]
[tex]Total\ value = \frac{21000}{30}[/tex]
Total value = 700
Therefore the total number of people at the movie theatre is 700.
