Writing and Graphing One-Variable Inequalities

It is given that the world's tallest tree is $380$ feet. This means that the height of any other tree is to shorter than this. Thus, $l$ should be less than $380$ ft. $$\begin{array}{c}l<380\text{ ft}\end{array}$$ Let's convert $380$ feet to inches since $l$ is measured in that unit. We should multiply $380$ with $12$ since $1$ foot is $12$ inches. $$\begin{array}{c}380\cdot 12=4560\end{array}$$ Therefore, $l$ can be described with the following inequality. $$l<4560$$
