# If -1/5 of a number n is at most 21, what are the possible values of n? How do you write and solve an inequality to find n?

Solution: $n \ge - 105$. In interval notation expressed as $\left[- 105 , \infty\right)$
$- \frac{1}{5} \cdot n \le 21 \mathmr{and} - n \le 105 \mathmr{and} n \ge - 105$
Solution: $n \ge - 105$. In interval notation expressed as $\left[- 105 , \infty\right)$[Ans]
