Jim paid $3.99 for a 14ounce bag of cookies. What was the unit cost per pound?

Guy paid $3.59 for a 10ounce bag of cookies. What was the
unit cost per pound? 
$3.99/(7/8 lb) = $4.56 per lb for the 14 oz bag
$3.59/(5/8 lb) = $5.74/lb for the 10 oz bag. 
Peaches,
Please make sure you NEVER post personal information online ... on any websites. Not your email address, not your phone number, not your school's name, not anything. It's not safe.
