Question 15. Stephanie has three books. A blue book, a yellow book, and a red book. The yellow book has four more pages than the red book. It also has seven more pages than the blue book. How many pages fewer than the red book does the blue book have? To solve this, let's start off with an assumption. Let's assume that the yellow book has 10 pages. We could make this number as big as we want, so long as it is bigger than seven, since we know that the yellow book must have seven more pages than the blue book. Next, let's take a look at the previous sentence. The yellow book has four more pages than the red book. To find out how many pages the red book has, we do 10 minus 4, and we get the red book has six pages. Next, we know the yellow book has seven more pages than the blue book. We can follow the same logic, 10 minus 7, and then we get that the blue book would have three pages. So, how many pages fewer than the red book does the blue book have? We know the red book has six, and the blue book has three, so we would do 6 minus 3, which would give us our answer, which is A, three.
