Sales Data Average Calculation

The problem requires calculating the average number of shoes sold based on specific data points: Salesman B on Thursday, Salesman E on Saturday, and Salesman D on Tuesday. This involves extracting these values from the relevant data source and then applying the formula for the arithmetic mean.

Required Sales Figures

First, identify the number of shoes sold for each required instance. These values must be obtained from the provided dataset (e.g., chart or table, which is assumed here).

• Salesman B on Thursday
• Salesman E on Saturday
• Salesman D on Tuesday

For the purpose of demonstrating the calculation, let's assume the following values were extracted:

Average Calculation Steps

The average is calculated by summing the values and dividing by the count of the values.

1. Sum the Sales Data: Add the number of shoes sold for the three specified data points.

   Sum = Sales(B, Thu) + Sales(E, Sat) + Sales(D, Tue)

   Sum = $70 + 74 + 60$

   Sum = $204$

2. Calculate the Average: Divide the total sum by the number of data points (3 in this case).

   Average = $\frac{\text{Sum}}{\text{Number of Data Points}}$

   Average = $\frac{204}{3}$

   Average = $68$

Therefore, the average number of shoes sold for these specific salesman-day combinations is 68.
