Answer:
525 children attended the concert.
Explanation:
Given that:
Total number of people who attended concert = 2500
Adult females = 47%
Adult males = 32%
Percent of children = (100-47-32)% = 21%
Number of children = 21% of people who attended
Number of children =
![(21)/(100)*2500](https://img.qammunity.org/2022/formulas/mathematics/high-school/7uu5na115utr137rd3kushtkaz0g2n5n67.png)
Number of children = 0.21*2500 = 525
Hence,
525 children attended the concert.
