    c. 12x - 24 = 60

    Step-by-step explanation:

    x is the number of boxes Krys bought.

    12x is the number of pastries in those boxes. 2·12 = 24 is the number of pastries in the boxes Krys kept for herself. Then the number of pastries Krys brought to the party is ...

    ... 12x - 24

    We are told that number is 60, so we can use this equation to find x:

    ... 12x - 24 = 60
