Six gross of special drawing pencils were purchased for use in a department. If the pencils were used at the rate of 24 a week, the maximum number of weeks that the 6 gross of pencils would last is?

Answer 1

If I recall, a gross is defined to be 144
so they bought 6(144) or 864 pencils
at a weekly use of 24 pencils,
the number of weeks = 864/24 or 36

Answer 2

Correct 144 to a gross.

Answer 3

36
