Answer:
TC (A) = 40x , TC (B) = 500 + 20x 
Step-by-step explanation:
Let the number of students be = x 
Hall A Total Cost
Relationship Equation, where TC (A) = f (students) = f (x)                                40 per person (student) = 40x 
Hall B Total Cost
Relationship Equation, where TC (B) = f (students) = f (x)                          500 fix fee & 20 per person (student) = 500 + 20x
