Using a hint is okay. It just tells the trainer to give you a little more review.

compute lower and upper possible values.

Bounds must use half-unit rounding interval.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Half of the rounding unit is the possible error in either direction.
2. Subtract half for the least possible value and add half for the upper cutoff.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Giving an answer that does not satisfy this rule: Accept correct lower bound and upper bound interval.
