Last month, in an attempt to improve my productivity, I began to write daily. The maximum number of pages I have time to write on any particular day is 10 pages, but my aim is to maintain an average of at least 6 pages per day. After 12 days my average was just under 7 pages per day, then the following day I increased my average to just over 7. Since then (for the last 8 days, up to and including today) I have been able to write only 3 pages each day. What is the minimum number of days from now until I can bring my average back up to 6 pages per day?
