Question

Option 1:3 1/3 lb. Of turkey for $10.50

Option 2:2 1/2 lb. of turkey for $6.25

Answer 1

Option #1

$10.50 divided by (3 + 1/3) = $10.50 divided by 10/3 = $10.50 * 3/10 = $10.50/10*3 = $1.05*3 = $3.15 / lb

Option #2

$6.25 divided by (2 + 1/2) = $6.25 divided by 5/2 = $6.25 * 2/5 = $6.25/5 * 2 = $1.25*2 = $2.50 / lb

Option #2 is cheaper
