B. The cost to rent the hill.
C. The total cost of the food.

Answer 1

The answer is B. The cost to rent the hill

Answer 2

The answer is B. The quantity that is NOT a variable is the cost of renting the hall. No matter how many people show up or how much food is required, this value will stay the same. The number of people, as stated in the question, is unknown which makes it a variable. This connects with the amount of food needed; It depends on the amount of people, which makes it also a variable quantity.
