To solve the inequality \( 28 > 4n \), we first rearrange it to isolate \( n \).
- Divide both sides by 4: \[ \frac{28}{4} > n \] This simplifies to: \[ 7 > n \] or equivalently, \[ n < 7 \]
Thus, the possible values of \( n \) are all real numbers less than 7. In interval notation, this can be expressed as:
\[ (-\infty, 7) \]
So, all possible values of \( n \) are \( n < 7 \).
