Quizplus · Accepted Answer

Number of Pens | Number of Panels Needed
-------------- | ----------------------
1             | 2
2             | 4
3             | 6
4             | 8
5             | 10

To find the number of panels needed for 10 pens, we can continue the pattern in the table and see that for each additional pen, we need two more panels. Therefore, for 10 pens, we would need:

2 + (2 x 9) = 20

So the answer is Choice C: 20 panels.
