Answer 2

Answer:

$2$ children, $9$ adults

Step-by-step explanation:

Let

x------> the number of adult tickets

y-----> the number of children tickets

we know that

$x+y=11$ ----> equation A

$22x+15y=228$ --------> equation B

Using a graphing tool

see the attached figure

Remember that

The solution of the system of equations is the intersection point both graphs

The solution is the point $(9,2)$

that means

$9$ adults

$2$ children
