To find the answer to this kind of problem, you need to find the cost-per-ounce of the different cereals, then you will be able to make a valid comparison of the various costs.
To find the cost per (means divided by) ounce, you will divide the given cost by the number of ounces of the product.
1) 2.39%2F15+=+0.1593 This one is $0.1593 per oz.
2) 2.87%2F18+=+0.1594 This one is $0.1594 per oz.
3) 3.79%2F24+=+0.157916 This one is $0.1579 per oz.
4) 5.10%2F32+=+0.159375 This one is $0.159375 per oz.
It appears that number 3) is the least cost per ounce and thus the best deal.
This is the 24-oz box.
