Answer to Problem 107AYU

$21 < x < 30$

Explanation of Solution

Given:

A young adult may be defined as someone older than 21 but less than 30 years of age.

Calculation:

Let a young adult age be $x$.

A young adult may be defined as someone older than 21, therefore $x > 21$

A young adult may be defined as someone less than 30 years, therefore $x < 30$

Hence $21 < x < 30$
