Full solution stays hidden until you ask for it.
1. Identify independent and dependent variables.
2. Find the constant rate and initial value.
3. Write dependent variable equals rate times input plus initial value.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
