Answer:
2.5 decor pieces per minute
Step-by-step explanation:
We know that rate of change is defined as:
(change in y) / (change in x)
= rise / run
We can identify rise and run as:
rise = 5 decor pieces
run = 2 minutes
Hence:
rate of change = (5 decor pieces) / (2 minutes)
rate of change = 2.5 decor pieces per minute
