Answer:
3 lb package for $5.25
Explanation:
Find the price per pound of each price:
$5.25 / 3 lbs = $1.75 per lb
$3.60 / 2 lbs = $1.80 per lb
And compare them:
$1.75 < $1.80
This means that the 3 pound package is a better deal, as an equivalent amount of chicken costs less in that package than in the 2 pound one.
