    Given:

    Christopher scores 2 goals in a soccer game.

    His goal total can vary from the average by 1 goal.

    To find:

    The absolute value equation can be used to calculate Christopher’s maximum and minimum goals per game.

    Solution:

    Let Christopher scores x goals in a soccer game.

    Then difference between actual goals and average goals is x-2.

    His goal total can vary from the average by 1 goal.

    Maximum number of goals = 2+1 = 3

    Minimum number of goals = 2-1 = 1

    It means, the difference between actual goals and average goals is either -1 and 1.

    x-2=-1        …(1)

    x-2=1         …(2)

    Using (1) and (2),we get

    |x-2|=1

    Therefore, the correct option is C.
