1 answer

To model the situation with linear equations, we can define two variables:

  • Let \( g \) represent the number of students receiving gift cards for excellent grades.
  • Let \( a \) represent the number of students receiving gift cards for perfect attendance.

We know the following from the problem:

  1. The total number of students is 100.
  2. The total cost of the gift cards is $4,000.

Based on this information, we can write the following equations:

  1. For the total number of students: \[ g + a = 100 \]

  2. For the total cost of the gift cards: \[ 40g + 25a = 4000 \]

Thus, the pair of linear equations that model this situation is: \[ \begin{align*}

  1. & \quad g + a = 100 \
  2. & \quad 40g + 25a = 4000 \end{align*} \]
