Solve the problem. Some friends decide to throw a party. It will cost $200 to rent a recreation hall and it will cost $18 per person for drinks and snacks. Let P(n) represent the per person cost (in dollars) if there are n people who go to the party. Find P(40). What does your result represent in terms of the party?
A. P(40) = 21. This means that if 21 people go to the party, the per person cost will be $40. B. P(40) = 23. This means that if 23 people go to the party, the per person cost will be $40. C. P(40) = 23. This means that if 40 people go to the party, the per person cost will be $23. D. P(40) = 5.45. This means that if 40 people go to the party, the per person cost will be $5.45.
