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.
