To determine which jar is the better buy, we need to compare their unit prices. The unit price is the price per unit of the product (in this case, per ounce). To find the unit prices, divide the price of the jar by its weight.
For the 8 ounce jar:
Unit price = $8.95 / 8 = $1.11875 per ounce
For the 10 ounce jar:
Unit price = $12.00 / 10 = $1.20 per ounce
Comparing the unit prices, we can see that the 8 ounce jar has a lower unit price ($1.11875 per ounce) compared to the 10 ounce jar ($1.20 per ounce).
Therefore, the better buy would be the 8 ounce jar.
To find the difference in the unit prices, subtract the unit price of the 8 ounce jar from the unit price of the 10 ounce jar:
$1.20 - $1.11875 = $0.08125
Rounding to the nearest cent, the difference in the unit prices is $0.08.
So the answer is:
A. 8 ounce jar; $0.08
