Answer 1

Answer: C. 120!

Explanation:

Okay so, first we need to find out our percentages of course.
I learned this trick that can help us with this question easily!

14% of 500 - 70 - Drama
14 * 5 = 70.

22% of 500 - 110 - Sports
22 * 5 = 110

20% of 500 - 100 - Reality
20 * 5 = 100

20% of 500 - 100 - Sci-fi
20 * 5 = 100

70 + 110 + 100 + 100 = 380

500 - 380 = 120

Therefore, documentaries is labeled as 24% of 500 or 120 out of 500.
