Final answer:
The question asks for the average percentage of Drive-Thru sales, but the information provided does not include relevant data for this calculation, therefore an accurate answer cannot be provided with the given datasets.
Step-by-step explanation:
The question presented does not provide enough information regarding the exact percentage of sales coming through the Drive-Thru specifically. However, the information provided pertains to various market shares of companies that replace automobile windshields, salespersons' car sales in a week, the number of major purchase store visits, statistical product use confidence intervals, meal consumption patterns, and a statistical analysis of car ownership within a community.
For precise calculations, such as determining the average percentage of Drive-Thru sales, data on both the total sales and the portion of those sales attributed to Drive-Thru transactions would be required. As this specific data is not provided, accurately calculating the average percentage of sales coming through Drive-Thru is unattainable based on the information at hand.
