Explanation:

Cost of 8oz bottled water = $0.89

[tex]\begin{gathered} \text{Unit Rate=}\frac{\$0.89}{8} \\ \$0.11\text{ per oz} \end{gathered}[/tex]

Cost of 16 oz bottled water = $1.09

[tex]\begin{gathered} \text{Unit Rate=}\frac{\$1.09}{16} \\ \$0.068\text{ per oz} \end{gathered}[/tex]

Cost of 24 oz bottled water = $1.89

[tex]\begin{gathered} \text{Unit Rate=}\frac{\$1.89}{24} \\ \$0.08\text{ per oz} \end{gathered}[/tex]

Cost of 32 oz bottled water = $2.39

[tex]\begin{gathered} \text{Unit Rate=}\frac{\$2.39}{32} \\ \$0.07\text{ per oz} \end{gathered}[/tex]

Therefore, the bottle that costs the least per ounce is the 16 ounce bottle.
