Problem number five. At the entrance of the zoo there are 12 children in line. Lucy is the seventh from the front and Sam is the second from the back. How many children are there between Lucy and Sam in the line? A-2, B-3, C-4, D-5, E-6. This problem has a picture. Let's make sure we can use it by counting that there are in fact 12 people in this line. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12. We're not going to count the dog. I'm going to cross them out so it doesn't confuse us. Now we will find Lucy by counting from the front. We'll find Sam counting from the back and see how many people are between them. Lucy is the seventh from the front. This is the front of the line. It's 1, 2, 3, 4, 5, 6, 7. Here's Lucy who's seventh. Now Sam is the second from the back. So this is the person that's in the very back. So this would be the second person from the back. So this guy is Sam. Now I've circled them and we see that there are 1, 2, 3 children between them. So our answer is 3 which is letter choice B.
