    The correct answer is B. 10 packs.

    Step-by-step explanation:

    1. Let's review the information provided to us to answer the question correctly:

    Number of students = 28 in each class

    Number of classes = 7

    Number of adults = 12

    Number of buying tickets per pack = 20

    2. How many packs of tickets should Mr Rogers buy?

    Let's find the number of tickets to the zoo necessary, this way:

    Number of tickets = Number of classes * Number of students + Number of adults

    Number of tickets = 7 * 28 + 12

    Number of tickets = 196 + 12

    Number of tickets = 208

    If Mr. Rogers buys 10 packs, it will be enough for all the students and 4 teachers. Buying additional 8 individual tickets would be for sure less expensive than buying 20 packs, unless the group is planning a second visit later.

    The correct answer is B. 10 packs.
