Answer:

Each child admissions ticket was sold for $69.94

Explanation:

At the movie theater, child admissions is $5.70 an adult admission is $9.20 on Sunday.

If each child admissions ticket is represented as c and each adult admission is represented as a, then, this means that:

123 tickets were sold. This means that:

c + a = 123______ (1)

and they were sold for a total of $886.60. This means that:

5.70c + 9.20a = 886.60_____ (2)

We have two simultaneous equations:

c + a = 123 _______________(1)

5.7c + 9.2a = 886.8_________(2)

From (1):

a = 123 - c _______________(3)

Putting (3) in (2), we have that:

5.7c + 9.2(123 - c) = 886.8

5.7c + 1131.6 - 9.2c = 886.8

Collecting like terms and simplifying:

=> 9.2c - 5.7c = 1131.6 - 886.8

3.5c = 244.8

c = 244.8 / 3.5

c = $69.94

This means that each child admissions ticket was sold for $69.94.
