Workers Inc. just bought 12 boxes of pens to put in their storage room for
employees to use as needed. Each box contains 40
pens. If each of the 41 employees working for Workers Inc. takes 3 pens when they are first brought into the office, how many pens
will be left in the storage room?
If there is 12 boxes of 40 pens each then there is 480 pens in total. If each worker takes 3 pens then that would be 40 times 3 to get 123 pens taken away. So 480-123 is 357 pens left in storage.
