Mrs. Wilkinson can buy a 20-ounce box of cereal for $3,60 or a 28-ounce box of cereal for $4,20. Which is the better buy? Explain your reasoning

20-ounce box for 3,60 is the better deal, divide each ounce by how much it costs and you can figure out which is cheaper, 28 divided by 4,20=4,6… 7 20 divided by 3,60=5,5… 6, so 20 ounces for 3,60 is the better deal, hope this helps
