27 children, 70 adults

Step-by-step explanation:

Mega Movies hosted a film premiere on Friday and charged $9 for adults and $5 for children.

97 adults and children attended, and a total of $765 was made in ticket sales.

Let's represent adults with a

Let's represent children with c

a + c = 97 i

9a + 5c = 765 ii

Multiply equation I by 9

Multiply equation ii by 1

9a + 9c = 873 iii

9a + 5c = 765 iv

Subtract equation iv from iii

4c = 108

c = 108/4

c = 27

There are 27 children

From equation I

a + c = 97

a + 27 = 97

a = 97-27

a = 70

There are 70 adults

70 adults and 27 children went to the film premiere.

Step-by-step explanation:

Let's call the number of adults A, and the number of children C.

The total number of people were 97, so:

A + C = 97

The total earning was $765, so:

9A + 5C = 765

From the first equation:

A = 97 - C

using this value in the second equation:

9*(97 - C) + 5C = 765

873 - 9C + 5C = 765

4C = 108

C = 27

Then we find the value of A:

A = 97 - C = 97 - 27 = 70

70 adults and 27 children went to the film premiere.
