Wesley is 15 and his sister Breenah is 7 . The sum of their ages is 22 . In how many years will the sum of their ages be double what it is now?
(A) 7
(B) 8
(C) 15
(D) 14
(E) 11
The sum of Wesley's and Breenah's ages is 22 .

After each year, each of their ages increases by 1 , so the sum of their ages increases by 2 .

For the sum to increase from 22 to $2 \times 22=44$, the sum must increase by 22 , which will take $22 \div 2=11$ years.

ANSWER: (E)
