Question 151608
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) {{{2.39/15 = 0.1593}}} This one is $0.1593 per oz.
2) {{{2.87/18 = 0.1594}}} This one is $0.1594 per oz.
3) {{{3.79/24 = 0.157916}}} This one is $0.1579 per oz.
4) {{{5.10/32 = 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.
