Let’s say your trying to get 100 pieces of gum.
The 20 pack:
0.75 cent/p
Times this by five, giving you 3.75
The ten packs:
There are 10 packs of gum which contain ten pieces of gum in one pack
10 times 10 is 100 pieces.
So 100 pieces is $5
But the deal for the 20 pack is 3.75
Making it the better deal
