Answer- The one pound package is a better deal because it costs 32 cents per ounce rather than the 20 oz, which charged 45 cents per oz.
Explanation- let’s convert all units to ONE OUNCE. 3.59/20(oz)= 0.45, do 45 cents per ounce for the first. For the second, we know that one pound is 8 oz so divide 2.59 by 8 and you get 32 cents per oz. We know that if we are getting 8 oz for 32 cents per ounce, it is the better deal rather than 45 cents per oz.
