Answer:
depreciation is $3,333.33 per year
Step-by-step explanation:
Initially : date = 2006, worth = $34,500
Finally : date = 2009, worth = $24,500
if we let x = date and y = worth, we end up with two points (coordinates) on the x-y graph
i.e
Initial = Point 1 (2006, 34500)
Final = Point 2 (2009, 24500)
The rate of change is simply the slope, m of the line joining these two points
given by:
m = (34500 - 24500) / (2006-2009)
= 10000 / -3
= -3,333.33
hence the annual rate of depreciation is $3,333.33 per year
