a theater is presenting a program on drinking and driving for students and their parents or other responsible adults. The proceeds will be donated to a local alcohol information center. Admission is $6 for adults and $3 for students. However, this situation has two constraints. the theater can hold no more than 180 people and for every two adults there must be at least one student. How many adults and students should attend to raise the maximum amount of money?
