The person
who is most likely to be classified as "working poor" is Carol, a single mother who works 35 hours a week at a job that pays slightly above minimum wage. The term "working poor" refers to individuals or families who work but still struggle to make ends meet and live below the poverty line.
Carol's situation fits this definition as she is working, but her income is not sufficient to support herself and her family. Jim, a full-time student with a work-study job, may be considered financially challenged, but he is not considered working poor as he is not supporting a family.
Dolores, who has an advanced degree and works 40 hours a week, is unlikely to be classified as working poor as she is likely to earn a higher income. Similarly, Jason, who is working part-time as a construction worker so he can devote time to starting up a real estate business, is not considered working poor as he is not reliant solely on his part-time job to support himself.
