“”An individual comes across a wallet filled with seven hundred dollars.”

Here’s a rephrased version of your story:

A man discovers a wallet containing $700. A few days later, he sees an announcement about a wealthy man who lost his wallet and is offering a $50 reward for its return.

The man soon finds the owner and hands over the wallet. As the rich man counts the money, he remarks, “I see you’ve already taken your reward.”

Confused, the poor man replies, “What are you talking about?” The wealthy man insists, “This wallet had $750 in it when I lost it.”

An argument ensues, leading both men to court to resolve their dispute. The poor man presents his side first, followed by the wealthy man, who finishes his argument by saying, “Your Honor, I trust you believe me.”
