Question

You can buy a 40 oz jar of peanut butter for $5.25, or you can buy a 15 oz jar for $2.10. which is the better deal? If we find out the cost per ounce for each jar, then we can determine which is the better price. To do this, we need to divide. ALWAYS put "money on top".

Answer 1

To find the cost per ounce for the 40 oz jar, divide the price by the number of ounces: $5.25/40 oz = $0.13 per oz.

To find the cost per ounce for the 15 oz jar, divide the price by the number of ounces: $2.10/15 oz = $0.14 per oz.

Therefore, the 40 oz jar is the better deal because it has a lower cost per ounce.
