To find the average rate of change, we divide the change in price by the number of days:
Average rate of change = Change in price / Number of days
In this situation, the change in the price of shoes is -$91 and the number of days is 7.
Average rate of change = -$91 / 7
Therefore, the average rate of change for the situation is approximately -$13 per day.
Find the average rate of change for the situtation.
