    Answer: The system of inequalities that models this situation are

    p + b ≤ 30

    12.5p + 9.5b ≥ 300

    Step-by-step explanation:

    Let p represent the number of hours he works at the pizzeria.

    Let b represent the number of hours he works at the bookstore.

    He cannot work more than 30 hours per week in order to attend classes. This means that

    p + b ≤ 30
