Come up with a question and reasoning that would justify this answer: 19
The question is: Cori is 3 years old today. In 5 years, she will be one-third the age of her aunt. How old is her aunt today?
Step-by-step reasoning process: In 5 years, Cori will be 3 + 5 = 8 years old. In 5 years, Cori’s aunt will be 8 x 3 = 24 years old. Today, her aunt is 24 - 5 = 19 years old.
