# Chapter 4 - Proportions, Percents, and Solving Inequalities - 4.5 - Inequalities, Compound Inequalities, and Problem Solving - Problem Set 4.5: 37

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.
