3 1/2 lb. of turkey for $10.50

Or

2 1/2 lb. of turkey for $6.25

2.5 lbs of turkey.

Step-by-step explanation:

First, find out how much each turkey costs per pound.

$10.50 / 3.5 lbs = $3 per pound.

$6.25 / 2.5 lbs = $2.50 per pound.

2.5 lbs of turkey is cheaper per pound, so it is the better buy.
