To find the answer, here is the solution for this problem:
Let M be Mia's age and B for Brooke's age.
M = 2B + 3 
M + B < 30 

M = 30 - B 
30 - B = 2B + 3 
3B = 27 

B = 9
Therefore, Brooke's age is 9 years old. The correct answer would be option C. 
Hope this is the answer that you are looking for. Let me know if you need more help next time.
