Final answer:
To calculate the average daily sales in dollars, use the formula =AVERAGE(range), where range is the range of cells that contain the daily sales data.
Step-by-step explanation:
To calculate the average daily sales in dollars, you need to use the formula for calculating the average. In cell J3, you can use the formula =AVERAGE(range), where range is the range of cells that contain the daily sales data.
For example, if the daily sales data is in cells A1 to A30, you would enter =AVERAGE(A1:A30) in cell J3.
This formula will calculate the average of the daily sales values and display it in cell J3.
