OBJECTIVES OF ALLOCATION
Hallie and Ashley are planning a trip to Padre Island, Texas, during spring break. Members of the varsity volleyball team, they are looking forward to five days of beach volleyball and parasailing. They will drive Hallie's car and estimate that they will pay the following costs during the trip:

They have reservations at the Beach-Vue Motel, which charges $95 per night for a single, $125 per night for a double, and an additional $20 per night if a rollaway bed is added to a double room.
Hallie's little sister, Courtney, wants to go along. She isn't into sports but thinks that five days of partying and relaxing on the beach would be a great way to unwind from the rigors of school. She figures that she could ride with Hallie and Ashley and share their room.
Required:
1. Using incremental costs only, what would it cost Courtney to accompany Hallie and Ashley?
2. Using the benefits-received method, what would it cost Courtney to go on the trip?
