Final answer:

To find out if the youngest person is of legal age, determine the ages of Patricia, Cristal, and Ángel based on their given relationships.


Explanation:

The youngest person is not necessarily of legal age. To determine this, we need to find the ages of Patricia, Cristal, and Ángel. Given that Cristal has twice the age of Patricia and Ángel is 15 years older than Cristal, we can represent their ages as follows:

  1. Let Patricia's age be 'x'.
  2. Then, Cristal's age is '2x'.
  3. And, Ángel's age is '2x + 15'.

Since the sum of their ages is less than 85, we can set up the inequality 'x + 2x + 2x + 15 < 85'. By solving this inequality, we can find their ages and determine if the youngest person is of legal age.
