Use the equation to predict the car value 7 years after purchase.
Use the variables V for Value and y to represent the year since purchase.
Explain how you arrived at your answer.
car value depreciation: Graph of VALUE against YEAR
V=$20000; Y=0
V=18000; Y=YEAR 1
V=16000; Y=YEAR 2
V=14000; Y=YEAR 3
V=12000; Y=YEAR 4
V=10000; Y=YEAR 5
