The equation that does NOT represent its situation correctly 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 correct equation should represent the rate per hour as $30 (which would be represented by the term multiplying x) and the one-time bonus as $75. The correct equation should be:
**y = 30x + 75** (where $30 is the hourly rate and $75 is the bonus).
Thus, the mistake in this equation is that $75 should be added to the hourly earnings, not $30.
