Problem Two - P and J (yummmmmm)




Peanut Butter and Jelly 

As I was making peanut butter and jelly sandwiches the other day, I ran out of bread. I still had half a jar of peanut butter and close to three-quarters of a jar of jelly left. 

As I ran down to the freezer to get another loaf of bread, I started thinking about the number of sandwiches I could make with the individual ingredients. A loaf of bread contains eighteen slices, though we do not like to have the heels (the ends) for our sandwiches so we always feed those slices to the birds. The 16-ounce jars of peanut butter will make 12 sandwiches, and the 48-ounce jars of jelly will make 60 sandwiches. 

(We like a little less jelly than peanut butter so the sandwiches aren't too "oozie"... but we always manage to end up with jelly on their clothes anyway!) 

If we were to start with a full loaf of bread and new jars of peanut butter and jelly, how many sandwiches could we make before emptying a bread bag and jars of jelly and peanut butter at the same time?
