Problem number 20, Laura, Iggy, Val, and Kate want to be in one photo together. Kate and Laura are best friends and they want to stand next to each other. Iggy wants to stand next to Laura because he likes her. In how many different ways can they pose for the photo if they all stand in one row? 3, 4, 5, 6, or 7. Kate and Laura want to stand together, but they can do it in one of these two ways. So we can have Kate on the right or on the left. If we have Kate and Laura like this on the left, then Iggy would want to stand here. And then we can have Val stand next to Kate. Or if Kate, Laura, and Iggy stand like this, Val could be here because Val does not care where he stands. And over here on the right, Iggy would stand there next to Laura. And then Val would stand there next to Iggy. Or Val could stand next to Kate. So we see here that there are four different ways in which they could pose for the photo. Which means our answer is B, 4.
