Final answer:
All scenarios result in losses for the Yoga Center; long-term operation is not advisable. Scenario 3 has the smallest loss and should continue in the short run if needed.
Step-by-step explanation:
Yoga business channels do not have a universally highest-paying hourly rate as this can vary greatly based on client volume, location, and business model. However, based on the provided scenarios, each showing consistent financial losses, none of these situations offer a positive hourly rate, and the business should contemplate shutting down in the long run.
In the short run, the Yoga Center should remain open only in scenario 3, where revenue is high enough to cover marginal costs and results in the smallest loss.
