Let's define the variables:
- Let \( g \) be the number of students receiving gift cards for excellent grades.
- Let \( a \) be the number of students receiving gift cards for perfect attendance.
Based on the information given, we can write two equations:
-
The total number of students being recognized: \[ g + a = 100 \]
-
The total cost of the gift cards: \[ 40g + 25a = 4000 \]
So your pair of linear equations modeling the situation is:
- \( g + a = 100 \)
- \( 40g + 25a = 4000 \)
