To find out how much Maria will save per ounce by choosing the less expensive option, we first need to calculate the price per ounce for both the 12-ounce bag and the 60-ounce container.
-
Calculating the price per ounce for the 12-ounce bag:
- Price of the bag: $2.40
- Ounces: 12
- Price per ounce for the bag = \( \frac{2.40}{12} = 0.20 \) dollars per ounce.
-
Calculating the price per ounce for the 60-ounce container:
- Price of the container: $18.00
- Ounces: 60
- Price per ounce for the container = \( \frac{18.00}{60} = 0.30 \) dollars per ounce.
-
Comparing the two prices per ounce:
- Price per ounce for the bag = $0.20
- Price per ounce for the container = $0.30
-
Finding the savings per ounce:
- Savings per ounce = Price per ounce for the container - Price per ounce for the bag
- Savings per ounce = \( 0.30 - 0.20 = 0.10 \) dollars per ounce.
Thus, by choosing the 12-ounce bag over the 60-ounce container, Maria saves $0.10 per ounce.
