Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify what the input represents.
2. Remove impossible values such as negative time or fractional counts.
3. Apply capacity or endpoint restrictions from context.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Purely algebraic all-real domain when context limits inputs.
