A six-pack of soda costs $2.49, a 12-pack of soda costs $3.99, and a 24-pack of soda costs $5.49. Which pack has the lowest cost per unit?

All you have to do to get the answer is to divide each number by how many packs it is then you get your answer

Solve:-

Find unit price per pack.

6-Pack:-

2.49 : 6 = 0.41

$ 0.41 per can

12-pack:-

3.99 : 12 = 0.33

0.33 per can

24-pack:-

5.49 : 25 = 0.22

0.22 per can

The cheapest is 24-pack, because the unit price for that is the cheapest. After that pack is the 12-pack one because that is cheaper than the 6-pack. and last is the 6-pack.
