Let's define the variables:
C = ballroom rental fee
S = cost per student for the meal
For the Regal Hotel:
The ballroom rental fee is $500, so the equation is:
C(regal) = 500
The cost per student for the meal is $75, so the equation is:
S(regal) = 75
For the Green Hill Country Club:
The ballroom rental fee is $1000, so the equation is:
C(green hill) = 1000
The cost per student for the meal is $65, so the equation is:
S(green hill) = 65
Therefore, the pair of linear equations that represents this real-world problem is:
C(regal) = 500
S(regal) = 75
C(green hill) = 1000
S(green hill) = 65
