Answer:
The larger package (the one that weighs a pound) is the better buy. This is because it costs only $.15 an oz versus costing $.18 an oz as the second package does.
Explanation:
In order to find the price per oz of each package, you divide the cost by the number of oz. Since there is 16 oz in a pound, we know the first package has 16 oz. Now we can do the math for each package.
$2.40/16 = $.15
$1.50/8 = $.18
This shows that the first package is clearly a better deal.
