Answer 1

16 ounce bottle

Step-by-step explanation:

Cost of 8oz bottled water = $0.89

`\begin{gathered} \text{Unit Rate=}(\$0.89)/(8) \\ \$0.11\text{ per oz} \end{gathered}`

Cost of 16 oz bottled water = $1.09

`\begin{gathered} \text{Unit Rate=}(\$1.09)/(16) \\ \$0.068\text{ per oz} \end{gathered}`

Cost of 24 oz bottled water = $1.89

`\begin{gathered} \text{Unit Rate=}(\$1.89)/(24) \\ \$0.08\text{ per oz} \end{gathered}`

Cost of 32 oz bottled water = $2.39

`\begin{gathered} \text{Unit Rate=}(\$2.39)/(32) \\ \$0.07\text{ per oz} \end{gathered}`

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