Many grocery stores do this calculation for you nowadays on the price tags! :)

What you want to do is find the Cost per Ounce of cereal and look for the lowest number.

In the first case, you have $3.37 per 15.3 ounces

Thus take 3.37 / 15.3 and you get $0.2203 per ounce or 22 cents per ounce

In the second case you have $4.59 per 20 ounces

Thus take 4.59 / 20 and you get $0.2295 per ounce or almost 23 cents per ounce

So

**.***the smaller box actually has a slightly cheaper cost per ounce associated with it*
