For this case we must solve a system of equations with two variables represented by the tickets of students and adults of a school production.
We define the variables according to the given table:
- a: Number of tickets sold to adults
- c: Amount of tickets sold to children.
We then have the following system of equations:
From the first equation, we clear the value of the variable c:
Answer:
The value that could replace c in the table is:
Option C

First write the inequality: 15
4.75x +3.50
Then to solve, first subtract 3.50 from both sides to get:
11.504.75x
Then divide by 4.75 to get 2.42, and since you can't buy .42 of a bag of fruit, you round down. So your final answer would be 2 bags of fruit.
