Rachel bought 2.5 pounds of cookies for $13.40. Her friend buys 4.5 pounds of crackers for $24.75. Which is less expensive per pound? By how much? (HINT: Find the unit rate for each, then find the difference)

Cookies: $13.40 divided by 2.5 = $5.36
Crackers: $24.75 divided by 4.5 = $5.50
Therefore, Cookies are less.

The answer would be the crackers are more expensive per pound and by $0.14. if you divide the price of the cookies by the amount of pounds you would come up with about $5.36 per pound. and if you do the same with the crackers it would be about $5.50 per pound.
