To determine the better buy, we can compare the unit prices of the two jars.
Unit price = Total price / Size
For the 8 ounce jar:
Unit price = $8.95 / 8 = $1.11875
For the 10 ounce jar:
Unit price = $12.00 / 10 = $1.20
Comparing the unit prices, the 8 ounce jar has a unit price of $1.11875, and the 10 ounce jar has a unit price of $1.20.
The better buy is the jar with the lower unit price, which is the 8 ounce jar.
To find the difference in unit prices:
Difference = Unit price of 10 ounce jar - Unit price of 8 ounce jar
Difference = $1.20 - $1.11875 = $0.08125
Rounding to the nearest cent, the difference in unit prices is $0.08.
Therefore, the correct answer is C. 10 ounce jar; $0.08.
