Answer:

The correct answer is D.

Explanation:

Let us first write this in a proportional relationship manner:

13 : 7 = x : 98

Now, the easiest way to deal with this kind of problem is to multiply the two outer parts of the proportional relationship on one side and two inner parts on the other side. So:

13 • 98 = x • 7

From here, it's easy to find x:

x = 13 • 98 / 7

x = 182
