Answer:

Jaylen was 16 years old. She's the oldest.

Step-by-step explanation:

16 Jaylen

15 sibling 1

14 sibling 2

13 sibling 3

12 sibling 4

11 sibling 5

10 sibling 6

____________

91 Total

My thinking was that I started out dividing 91 by 7. That came out 13. So I knew the oldest one had to be older than 13.
