    Thanks John Moffat for the lecture, is well explained. However, I have one small problem, I wish to know the difference between total time for the next 7 and total time for 7. In example 6 you calculated total time for the next 7 and got 237.5 and I tried to calculate total time for 7 using the formular I got 312.22 . I was hoping to get 237.5. So i was wondering if they don’t mean thesame thing.

      When it says the next 7 it means another 7 after the one already produced – so it bring the total up to 8.

      So to get the time for the next 7 you need to calculate the total time for 8 and then subtract the time it took for the first one.

    In the last part of the question where the total time for the 30 batches was calculated, why was the average time of 90.80 multiplied by 30 to get 2,724?
    I thought the average time of 90.08 which was calculated for the 30 batches would have been used.
