2. Unit pricing. It is probably listed on the shelf but you can do it yourself anyway.
Both boxes will have the mass of cereal contained in each. Say box A is 1 kilogram and box B is 2 kilograms
Say box A costs 1 dollar and box B costs 1.50 dollars
then
Box A costs 1 dollar per kilogram and box B costs 1.50/2 = 0.75 dollars per kilogram

Obviously box B costs less per kilogram.

6. You can, find out the unit rate or the cost per ounce. Then, you can divide the cost of the first box / box #1 by the number of ounces in that box and do the same thing with the other box / box #2. I hope this helps!
