Which is the better buy 3 pounds for $8.31 or 5 pounds for $12.95

The better buy would be 5 pounds for $12.95 because if you multiply how much 5 pounds cost twice it’s $25.90 and if you multiply how much 3 pounds cost times 3 to get $24.93. Now this is the confusing part. If you figure out how much one pound is of the 3 pound buy it would be $2.77 now to get to 10 pounds altogether you have to add that extra pound to the 3 pounds times 3 so that would make it $27.70 and it’s only 25.90 for the 5 pounds times 2 .Hope I could help if I was wrong let me know !!

3 pounds for $8.31

$8.31 / 3 = $2.77

Each pound is $2.77.

5 pounds for $12.95

$12.95 / 5 = $2.59

Each pound is $2.59

The better deal is 5 pounds for $12.95,

Hope this Helps!!
