The number of kids in your group is 12.
Step-by-step explanation:
Given, 
Number of people = 20 
Cost of each kid ticket = $4 
Cost of each adult ticket = $6 
Total spent = $96 
Let, 
x be the number of kids ticket 
y be the number of adult ticket 
According to given statement; 
x+y=20     Eqn 1
4x+6y=96    Eqn 2
Multiplying Eqn 1 by 4

Subtracting Eqn 3 from Eqn 2

Dividing both sides by 2 

Putting y=8 in Eqn 1 

The number of kids in your group is 12.
