Answer:  15 packs per hour

======================================================

Work Shown:

y = change in number of packs sold

y = 57 - 12

y = 45 packs

x = change in time (in hours)

x = 3 hours

m = slope = rate of change

m = y/x

m = 45/3

m = 15

The store sold 15 packs per hour during the timespan of noon to 3:00 pm.
