The value of a share of stock decreased $96 over the last 8 days. Find the average rate of change in dollars per day.
To find the average rate of change, we divide the total change in value by the number of days over which the change occurred.
The total change in value is $96 and the number of days is 8.
Therefore, the average rate of change in dollars per day is $\dfrac{96}{8}=\boxed{12}$.
To find the average rate of change in dollars per day, we need to divide the total change in value by the number of days.
Total change in value = $96
Number of days = 8
Average rate of change = Total change / Number of days
Average rate of change = $96 / 8
Dividing, we find:
Average rate of change = $12
Therefore, the average rate of change in dollars per day is $12.
