A company replaces their cars every 6 years. A car is worth $13520 after 2 years. The company uses a depreciation rate of 35% a year.

if the initial value is v,
v - .35(2) = 13520
Now, knowing v, after n years the car is worth
v(1 - .35n)
Note that the car is fully depreciated after only 3 years, if the depreciation is 35% of the full value each year.
