Step-by-step explanation:
A cost benefit analysis might be a helpful tool to spot cause and effect relationships between various activities and cost drivers. This analysis involves comparing the costs and benefits of a decision or project to determine if the benefits outweigh the costs. By weighing the marginal costs and benefits, which are the extra costs and benefits of adding an additional unit, one can make an informed decision. The cost benefit analysis can be represented using a T-shaped chart, with costs on one side and benefits on the other.
