Which is better to buy, 3 pounds for $8.31 or 5 pounds for $12.95? Explain

It better to buy 3 pounds cause if you dont want to spend a lot of money you would buy the cheaper one

3 pounds for $8.31 because not only is it cheaper but you can buy more packages for less ... Meaning if you were to buy 2 of the 3 pound packages than it would come out to about 17 dollars where as if you were to buy 2 of the 5 pound packages it would come out to about 25 dollars ...
