Explanation:

Let

x-----> the number of child tickets

y----> the number of adult tickets

we know that

`x+y=151` -----> equation A

`6x+9.80y=1,122.60` -----> equation B

Solving by graphing

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

The intersection point is (94,57)

see the attached figure

therefore

The number of child tickets was 94

The number of adult tickets was 57
