What is a reasonable assumption when replacing a long-term employee with a higher compensated assistant?

When replacing a long-term employee with a higher compensated assistant, the assumption that increased sales will offset higher expenses is reasonable because the new assistant may bring additional skills, innovative ideas, or a stronger network that can enhance business operations. Their higher compensation could be justified with the expectation that they will contribute to generating more revenue, thus balancing or surpassing the additional costs associated with their salary.

This approach recognizes the potential positive impact of investing in talent and how it can lead to improved performance and greater sales. If the new assistant possesses advanced expertise or experience in customer service and sales strategies, for example, their presence could lead to increased customer satisfaction and more sales, effectively mitigating the higher expense of their compensation.

In contrast, the other options do not directly correlate with the implication of cost and revenue dynamics established by hiring a new assistant. Increasing promotional events, changing the cost of goods sold, or predicting greater shop traffic does not inherently follow from merely changing personnel; those outcomes depend on various external factors as well as the effectiveness of the new hire in driving those specific results.
