Question

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

Answer 1

Find the unit rate for each

$8.31/3 pounds= $2.77 per pound

$12.95/5 pounds= $2.59 per pound

Final answer: The second option is better because you are paying less per pound (2.59<2.77).

Answer 2

We can find the answer by dividing each price by the amount of pounds and then seeing which number is bigger. Lets try...

8.31/3=2.77

12.95/5=2.59

Since the 12.95 deal allows you to get one pound for just 2.59, that is the better deal.

Hope this helps!
