The lower bound is 0.11% - 0.01% = 0.10%
0.10% of 100,000 = 0.001*100000 = 100
100 boxes is the fewest errors made.

The upper bound is 0.11% + 0.01% = 0.12%
0.12% of 100,000 = 0.0012*100000 = 120
120 boxes is the most errors made

The number of errors per day spans from 100 to 120.
Multiply each value with 5 if working with a 5 day week, or use 7 instead. It will depend on context given by your teacher.

~~~~~~~~~~~~~~~~~~

The answer depends on how many working days are there in one week,

but for some unknown reason, the problem does not disclose this information,

therefore, we, the tutors, are in trouble.

I would say that the question is not quite relevant to the supplied data,
and this makes a painful impression on me.
I'm not used that the authors do not care so much about readers.
In my textbooks, this was never the case.

In my time, it was unimaginable that the authors of a textbook were so sloppy.

They would have been kicked out of everywhere the next day.

Without the right to recovery.
