3 1/3lb. of turkey for $10.50

2 1/2lb. of turkey for $6.25

3 1/3 Ib = 10/3 lb

10 1/2 dollars = 21/2 dollars

A: Cost of one lb of turkey = (21/2) / (10/3) = 3.15 dollars

2 1/2 lb = 5/2 lb

6 1/4 dollars = 25/4 dollars

B: Cost of one lb of turkey = (25/4) / (5/2) = 2.5 dollars

Therefore choice B is cheaper
