96 people are attending the concert.
Step-by-step explanation:
Given,
Number of children at concert = 12
This represents 12.5% of the people attending concert.
Let,
p be the total people attending concert.
12.5% of p = 12
[tex]\frac{12.5}{100}*p=12\\0.125p=12[/tex]
Dividing both sides by 0.125
[tex]\frac{0.125p}{0.125}=\frac{12}{0.125}\\p=96[/tex]
96 people are attending the concert.
