assuming your asking about #64, you have to divide $8.64 by 12 to get the unit price. This comes out to $0.72 which after comparing to the 1-quart container, $0.89. You will find the 12 one- quart container is a better deal because it costs less. To find how much money is saved, solve $0.89 - $0.72. This leaves you with a savings of $0.17 per quart.
ANSWER: $0.17
