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

The answer to this problem is 3 loaves and here's why:

If Rosa and Clarice are making sandwiches for the students and the teacher, that is 24 people in total. Each loaf of bread has 16 slices. However, the two end pieces aren’t being used, bringing the total number of used slices per loaf of bread to 14. If we know that a sandwich has 2 slices of bread, then we can figure the problem out by multiplying the 2 by the number of people eating the sandwiches (so 24 * 2 = 48). Then we divide the total number of slices used by the number of slices per loaf of bread (so, 48 / 16 = 3). So, for the sandwiches, Rosa and Clarice will need 3 loaves of bread.

answer: 2530
