Solve:-
Find unit price per pack.
6-Pack:-
2.49 ÷ 6 = <span>0.41
$</span><span>0.41 per can
12-pack:-
3.99 </span>÷ 12 = 0.33
<span>0.33 per can
24-pack:-
5.49 </span>÷ 25 = <span>0.22
</span><span>0.22 per can
</span>
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. <span />
