Problem 92 of 7
Decide whether proposed input p=18 is meaningful for context R(p)=p(30-p) for prices 0 <= p <= 30.
Using a hint is okay. It just tells the trainer to give you a little more review.

Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify the context domain.
2. Compare the proposed input to the domain restrictions.
3. State whether it is meaningful and why.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Numerical evaluation without checking whether the input is allowed.
