Step-by-step explanation:
A cost-benefit analysis can help determine if there is a reasonable cost to use a child abuse hotline. Conducting a cost-benefit analysis involves weighing the costs and benefits of implementing the hotline. This can include considering the financial costs of operating the hotline, as well as the benefits of preventing and addressing child abuse through early intervention and support. Consulting with experts in the field of child abuse can provide valuable insights and expertise to inform the analysis. Researching the average cost of child abuse cases can also provide helpful data to consider in the analysis, such as the potential costs of not having a hotline in place.
