The equation that does NOT represent its situation is:
**y = 75x + 30**
- Sophia tutors students at a rate of $30 per hour. She also received a one-time sign-up bonus of $75 from the tutoring platform.
The equation implies that she earns $30 for every hour worked plus $75 for each hour, which is incorrect. The correct equation should be **y = 30x + 75**, indicating $30 per hour plus a one-time bonus of $75.
The other equations correctly match the situations described.
