Writing and Graphing One-Variable Inequalities

Let's call the weight $w$ for the junior lifters that do not qualify. It is given that the qualification limit is $400$ pounds for seniors, and $23$ pounds less for juniors. That is $$400-23=377\text{ pounds.}$$ The lifters that do not qualify must have bench-pressed less than $377$ pounds. We can write it as $$w<377.$$
