now, for option 2
Let
cost=1.25 dollars
number of ounces=12
replace
[tex]\begin{gathered} \text{unit rate=}\frac{total\text{ cost}}{N\nu\text{mber of oz}} \\ \text{unit rate=}\frac{1.25}{12}=0.104\text{ dollars per ounce=0.104}\frac{dol}{oz} \end{gathered}[/tex]the better deal is teh cheapest option,
