Step-by-step explanation:
Define
v = value after t years.
Therefore the linear model is
v = mt + c
where
m = depreciation rate
t = years since purchase
c = constant
When t=0, v = 20,000, therefore
20000 = m(0) + c
c = 20000
When t=10, v = 2000, therefore
2000 = 10m + 20000
-18000 = 10m
m = -1800
Answer:
The linear model is
v = -1800t + 20000
