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?

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.

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
