A sales rep worked 25 days last month, made 150 calls, and wrote 60 orders for a sales volume of $200,000. What is his batting average?

To determine the batting average of the sales rep, we use the formula for batting average in this context, which is calculated as the number of successful outcomes (orders written) divided by the total attempts (calls made).

In this scenario, the sales rep wrote 60 orders and made 150 calls. Thus, the batting average can be computed as follows:

[ \text{Batting Average} = \frac{\text{Orders Written}}{\text{Calls Made}} ]

Substituting in the values:

[ \text{Batting Average} = \frac{60}{150} ]

When we calculate this fraction:

[ \text{Batting Average} = 0.400 ]

This means that for every call the sales rep made, there was a 40% success rate in converting those calls into orders. A batting average of 0.400 demonstrates a proficient level of performance in sales activities, indicating that the sales rep is effectively closing a significant portion of the calls he makes. Therefore, the correct answer reflects a solid understanding of the effectiveness of the sales rep's efforts in converting calls into successful sales.
