Answer: 12-pound bag of cat food
Explanation:
12 pounds bag of cat food = $18
15 pounds bag of cat food = $24
Let's find the cost per pound of the 12-pound bag first
Take 18 divided by 12 = $1.50 per pound
Now find the cost per pound of the 15-pound bag
Take 24 divided by 15 = $1.60 per pound
So, buying a 12-pound bag of cat food is better because it is cheaper per pound.
