Final answer:
The 23.6-ounce bottle at $0.30 per ounce is the better buy compared to the 15.4-ounce bottle at $0.35 per ounce.
Step-by-step explanation:
To determine which bottle of olive oil is the better buy, we need to calculate the cost per ounce for each option.
For the 15.4-ounce bottle costing $5.39, we divide $5.39 by 15.4 ounces:
Cost per ounce for the 15.4-ounce bottle = $5.39 ÷ 15.4 ounces
= $0.35 per ounce
For the 23.6-ounce bottle costing $7.08, we divide $7.08 by 23.6 ounces:
Cost per ounce for the 23.6-ounce bottle = $7.08 ÷ 23.6 ounces
= $0.30 per ounce
Comparing the two, the 23.6-ounce bottle has a lower cost per ounce and is therefore the better buy.
