What is the average rate of change in the sales per day between the 2nd and 5th day?
To find the average rate of change in sales per day between the 2nd and 5th day, we first need to calculate the total change in sales and the total number of days between the 2nd and 5th day.
Total change in sales = ($310 - $220) = $90
Total number of days = 5 - 2 + 1 = 4 days
Now we can calculate the average rate of change:
Average rate of change = Total change in sales / Total number of days
Average rate of change = $90 / 4 days = $22.50 per day
Therefore, the average rate of change in the sales per day between the 2nd and 5th day is $22.50.
