What's the rate of change for this table
x/number of minutes: 5, 7, 11, 14
y/Number of items packed:20,28,44,56
A. the worker packed 8 items in boxes per minute
B. The worker packed 37 items in boxes per minute
C. The worker packed packed 4 items per minute
D. The worker packed 15 items per minute
To find the rate of change for the table, we will calculate the change in y (number of items packed) divided by the change in x (number of minutes).
Using the values from the table:
Change in x from 5 to 7 = 7-5 = 2
Change in y from 20 to 28 = 28-20 = 8
Rate of change = Change in y / Change in x
Rate of change = 8 items / 2 minutes
Rate of change = 4 items per minute
Therefore, the correct answer is:
C. The worker packed 4 items per minute.
