    Answer:

    11 weeks have passed.

    Step-by-step explanation:

    We can create a linear function that represents the number of bocadillos offered as a function of the number of weeks (s) that went by since the beginning (when the number of bocadillos was 6):

    f(s) = 6 + 2 * s

    Since now the number of bocadillos is 28, we can solve for s in the equation

    28 = 6 + 2 * s

    subtract 6 from both sides

    28 – 6 = 2 * s

    22 = 2 * s

    divide both sides by 2

    11 = s

    Therefore, 11 weeks have passed.
