Haylie Liu · Answer 1

Correct option is

C) 1500 people per event

Explanation:

To find the rate, you will need to first divide the number of casualties by the number of events needed to produce an impact.

I. e Number of casualties / Number of events needed to produce an impact

= 30,000,000/21000 =

30000/21 = 1429

Since 1429 is approximately 1500, it is the closest to the answer than any other option.

The correct answer is 1500 people per event.
