Answer:
the 8 pack
Explanation:
You need to figure out the price of each stick in the 8 pack, to do that you divide 3.99 by 8, even if the answer is a long decimal pay attention to the first two decimal places, if they are larger than the one stick, which in this case is $0.54, then the best price would be to get the 8 pack over 8 of the singles, and vice versa.
