Solution
Solution Steps
To solve this problem, we need to set up a system of linear equations based on the information given. Let \( c \) represent the number of children's tickets and \( a \) represent the number of adult tickets. We have two equations: one for the total number of tickets and one for the total cost. The equations are:
\( c + a = 1850 \) (total tickets)
\( 4c + 12a = 15800 \) (total cost)
We can solve this system of equations using substitution or elimination to find the values of \( c \) and \( a \).
Step 1: Set Up the Equations
We define \( c \) as the number of children's meal tickets and \( a \) as the number of adult meal tickets. Based on the problem, we can set up the following system of equations:
\( c + a = 1850 \)
\( 4c + 12a = 15800 \)
Step 2: Solve the System of Equations
We solve the system of equations to find the values of \( c \) and \( a \). From the first equation, we can express \( a \) in terms of \( c \):
\[
a = 1850 - c
\]
Substituting this expression into the second equation gives:
\[
4c + 12(1850 - c) = 15800
\]
Simplifying this leads to:
\[
4c + 22200 - 12c = 15800
\]
\[
-8c + 22200 = 15800
\]
\[
-8c = 15800 - 22200
\]
\[
-8c = -6400
\]
\[
c = 800
\]
Step 3: Find the Number of Adult Tickets
Substituting \( c = 800 \) back into the equation for \( a \):
\[
a = 1850 - 800 = 1050
\]
Final Answer
The number of adult meal tickets sold was \( a = 1050 \) and the number of child meal tickets sold was \( c = 800 \).
Thus, the final answers are:
\[
\boxed{a = 1050}
\]
\[
\boxed{c = 800}
\]
