Final answer:
The text 'Satyricon' by Petronius does not explicitly state the specific percentage of profits that Trimalchio gives to the god Mercury. This detail, if provided, might depend on the specific edition or interpretation of the text.
Step-by-step explanation:
The student's question is in reference to the character Trimalchio from the ancient Roman work of fiction ‘Satyricon’, written by Petronius. In the narrative, Trimalchio is known for his wealth and lavish banquets, and it is mentioned that he dedicates a significant portion of his profits to the god Mercury. The specific percentage that Trimalchio gives to Mercury is, however, not explicitly stated in the text as a numerical value, making this question somewhat tricky. If this is a question from a specific edition or interpretation of ‘Satyricon’ with added contextual details, the answer would typically be found within that context. It is important to review the source material carefully or any class notes that might indicate a specific interpretation provided by the teacher.
