Final answer:
To find the average tire sales per day, divide the total monthly sales of $12,437.89 by the number of days the shop was open, which is 26. The calculation gives an average sales per day of about $478.38.
Step-by-step explanation:
To calculate the average tire sales per day, you need to divide the total tire sales of the month by the number of days the shop was open. In this case, the shop's total tire sales for the month are $12,437.89 and it was open for 26 days.
The formula to find the average daily sales is:
Average daily sales = Total sales for the month / Number of days open
Using the given figures:
Average daily sales = $12,437.89 / 26
Now, performing the calculation:
Average daily sales = $478.38 (rounded to two decimal places)
Therefore, the average sales per day was approximately $478.38.
