now, in a 6-pack, there are 6 bottles, 6-pack.
in a 24-pack, there are 24 bottles, 24-pack.
so, if 6 bottles, cost 8.80, how much will it be for 24 bottles then?
[tex]\bf \begin{array}{ccll}
bottles&price\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
6&8.80\\
24&p
\end{array}\implies \cfrac{6}{24}=\cfrac{8.80}{p}\implies p=\cfrac{24\cdot 8.80}{6}[/tex]
