Find the price of each, then you'll know which costs the least.

"better buy" is not a clearly defined math term.

Not all cans of soda contain the same net contents. Usually a can will hold 12 fluid ounces but these days there are other sizes, too.

Assuming each can in any "packs" is the same net contents:

4.32%2F12 versus 4.16%2F13 as dollars%2Fcan;

0.36 versus 0.32;

The 13-pack for $4.16 gives the better money per can deal. The better buy.
Thirty-two cents per can is lower price than thirty-six cents per can.
