The Class Party Project
Mrs. Brown formed a committee of students to investigate sites for a class party. The committee does not know how many of the students will attend and has not yet decided whether each class member can invite a guest. However, they have brought back the following details on parties:
Water World – Swimming, hot dog, chips, and drink. Cost: $100 to reserve the pool and
$5 per person.
Cinema Café – Pizza, drink, and a movie. Cost: $10 per person.
Skate-a-Rama – Skating and ice cream (eat before you come). Cost $200 to rent the skating rink and $2 per person for skate rental.
Bowling Sphere – Unlimited bowling for 3 hours, drink. Cost $400, no additional charge per person.
If price is the primary focus of your decision, which party option is the best?
