which is a better deal: a 20 pack of gum for. 75 or a package of 10 packs of gum each containing 10 sticks for $5?

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
