Answer:
14
Step-by-step explanation:
Distance between y2 = x + 8 and y1 = x - 6
y2 - y1 = (x + 8) - (x - 6) = 14
For this case we propose a system of equations:
x: Let the variable representing the number of children in the concert
y: Let the variable representing the number of adults at the concert
According to the assistance we have:

According to the cost we have:

Substituting the first in the second equation we have:

Thus, the concert was 375 adults.
On the other hand we have:

Thus, the concert was 1125 children.
In total they were:
people
ANswer:
The concert was 1500 people
