$0.25 per ounce
To find out how much Mia saves per ounce by buying the 40-ounce jar, we first need to determine the cost per ounce for each jar.
The cost per ounce for the 40-ounce jar is $5.20 / 40 ounces = $0.13 per ounce.
The cost per ounce for the 15-ounce jar is $2.70 / 15 ounces = $0.18 per ounce.
Therefore, Mia saves $0.18 - $0.13 = $0.05 per ounce by buying the 40-ounce jar.
Therefore, the correct answer is $0.05 per ounce.
To find out how much Mia saves per ounce by buying the 40-ounce jar, we need to calculate the price per ounce for both jars.
For the 40-ounce jar:
Price = $5.20
Ounces = 40
Price per ounce = Price / Ounces = $5.20 / 40 = $0.13 per ounce
For the 15-ounce jar:
Price = $2.70
Ounces = 15
Price per ounce = Price / Ounces = $2.70 / 15 = $0.18 per ounce
To calculate the amount saved per ounce, subtract the price per ounce of the 40-ounce jar from the price per ounce of the 15-ounce jar:
Amount saved per ounce = $0.18 - $0.13 = $0.05 per ounce
Therefore, Mia saves $0.05 per ounce by buying the 40-ounce jar.
To find out how much Mia saves per ounce by buying the 40-ounce jar instead of the 15-ounce jar, we need to compare the cost per ounce for both options.
For the 40-ounce jar, Mia pays $5.20. Therefore, the cost per ounce is calculated as:
Cost per ounce = Total cost / Total ounces
Cost per ounce = $5.20 / 40
Cost per ounce = $0.13
For the 15-ounce jar, Mia pays $2.70. Therefore, the cost per ounce is calculated as:
Cost per ounce = Total cost / Total ounces
Cost per ounce = $2.70 / 15
Cost per ounce = $0.18
Now, to find out the amount Mia saves per ounce by buying the 40-ounce jar, we subtract the cost per ounce of the 40-ounce jar from the cost per ounce of the 15-ounce jar.
Savings per ounce = Cost per ounce (15-ounce jar) - Cost per ounce (40-ounce jar)
Savings per ounce = $0.18 - $0.13
Savings per ounce = $0.05
Therefore, Mia saves $0.05 per ounce by buying the 40-ounce jar instead of the 15-ounce jar.
