To create a pair of linear equations that represent this real-world problem, we can use the following variables:
C = ballroom rental fee\
s = number of students\
R = total cost at the Regal Hotel\
G = total cost at the Greenhill Country Club
For the Regal Hotel, the total cost is calculated by adding the ballroom rental fee and the meal cost per student:\
R = 500 + 75s
For the Greenhill Country Club, the total cost is calculated in the same way:\
G = 1000 + 65s
So, the pair of linear equations representing this real-world problem would be:
Equation 1: R = 500 + 75s\
Equation 2: G = 1000 + 65s
