One possible real-world interpretation of the inequality 4x + 15 < 120 could be:
Let x represent the number of hours you work per week at a part-time job. The inequality is stating that the total amount of money you earn per hour (4x) plus an additional $15 should be less than $120.
This means that your hourly wage multiplied by the number of hours worked plus $15 must be less than $120.
