Final answer:
After calculating the cost per ounce for both bottles, the 16-ounce bottle at $0.15 per ounce is cheaper than the 12-ounce bottle at $0.16 per ounce. Therefore, the 16-ounce bottle costs less per ounce.
Step-by-step explanation:
To find out which bottle of water costs less per ounce, you need to calculate the cost per ounce for each option.
For the 12-ounce bottle costing $1.92:
- Divide the total cost by the number of ounces: $1.92 / 12 ounces = $0.16 per ounce.
For the 16-ounce bottle costing $2.40:
- Divide the total cost by the number of ounces: $2.40 / 16 ounces = $0.15 per ounce.
Comparing the two, the 16-ounce bottle at $0.15 per ounce is cheaper than the 12-ounce bottle at $0.16 per ounce.
The 16-ounce bottle costs less per ounce.
