C.

14 children; 144 adults

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of children who went to the film premiere

y is the number of adults who went to the film premiere.

One hundred fifty-eight adults and children attended

This means that

They charged $9 for adults and $4 for children. $1,352 was made in ticket sales.

This means that

So

From the first equation

Replacing in the second equation

So the correct answer is:

C.

14 children; 144 adults

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
