Answer
The solution set is {n|n $\geq$ 4} , or [4, $\infty$) in interval notation.
Work Step by Step
We use the properties of inequalities to solve this inequality.
n $\geq$ 3.4 + 0.15n
n - 0.15n $\geq$ 3.4
0.85n $\geq$ 3.4
Divide both sides by 0.85 to obtain:
n $\geq$ 4
The solution set is {n|n $\geq$ 4} , or [4, $\infty$) in interval notation.
