Answer:
it could be about money in a banking account.
Step-by-step explanation:
person a is really good with money and has saved a lot. he has 100$ in his account. person b is okay with it, and has saved 25$. however, person c and d aren't so responsible and get carried away. person c has -12$, and person d has -20$.
