Rosa and Clarice realized they would have some bread left over (not including the end pieces), so they decided to make sandwiches for the librarian, office staff, and custodian. How many sandwiches will they be able to make? (Part 2 of Rosa and Clarice are making sandwiches for all the students in their class and their teacher. There are 23 students in their class. Each loaf of bread has 16 slices. They don’t want to use the slices on the ends of the bread, because most students don’t like them. If they make 1 sandwich for each student and for the teacher, how many loaves of bread will they need? Show all your work. (Hint: Don't forget to add the teacher. Also remember you can't buy half a loaf of bread, so how many whole loaves?) (The answer to The part 1 is 4 loaves of bread)
