To find the rate of change, we can take the difference in the number of items packed and divide it by the difference in time.
Between 4 minutes and 6 minutes, the worker packed 26 - 20 = 6 items.
Between 6 minutes and 12 minutes, the worker packed 44 - 26 = 18 items.
Between 12 minutes and 14 minutes, the worker packed 50 - 44 = 6 items.
Therefore, the rate of change is 6 items / 2 minutes = 3 items per minute.
The statement that describes the rate of change is: The worker packed 3 items in boxes per minute.
