Answer: D. y= 15/x
Explanation:
We have to test each explanation first, but I started with D because it is the most reasonable.
When you check the first column, you take 15 and divide it by 15. What do you get? 1.
1. X= 15 Y= 1 (15/15) = 1
When you check the second column, you take 15 and divide it by 5. What do you get? 3.
2. X= 5 Y= 3 (15/5) = 3
When you check the third column, you take 15 and divide it by 3. What do you get? 5.
3. X= 3 Y= 5 (15/3) = 5
When you use the fourth column, you take 15 and divide it by 1. What do you get? 15.
4. X= 1 Y= 15 (15/1) = 15
Since this all checks out, the answer is therefore correct.
