PLEASE HELP! If 2580 people watched one show and 2920 people watched another show. How many people need to watch the third show for there to be a 3000 people average attendance per show?

2,500 (maybe)

1st show=2580
2nd show=2920
Add(+)=5,500

1st and 2nd show=5,500
Average ppl=3000
Subtract (-)= 2,500

Answer:2,500 people

Answer:

3480

Explanation:

Set it up so it looks like this.

(2580 + 2930 + x )/3 = 3000 Combine the terms on the left

(5510 + x) / 3 = 3000 Multiply by 3

5510 + x = 9000 Subtract 5510

x = 9000 - 5510

x = 3490

Does that really work?

2580 + 2930 + 3490 = 9000

Which says it does work.
