    By arithmetic series, the cards will have the same 12 punches in one week.
    From that question, we know that the initial punches on Kimberly’s card are
    Initial Tea = 6
    Initial Coffee = 5
    For each week, Kimberly earns 6 punches for tea and 7 punches for coffee, Which means that we can use the arithmetic series for determining how much Kimberly earns punches for n-week.
    Tea = 6 + 6i
    Coffee = 5 + 7i
    where i is the number of weeks.
    The number of punches will be the same, hence we can write the equation to
    Tea = Coffee
    6 + 6i = 5 + 7i
    7i – 6i = 6 – 5
    i = 1
    Hence, the cards will have the same number in one week.
    Substitute the value of i to Tea
    Tea = 6 + 6i
    Tea = 6 + 6(1)
    Tea = 12 punches
    the total punches on each card are 12.
