Step-by-step explanation:
The formula for depreciation is as follows (I had to look it up too):
worth after time = initial worth * (rate)^t
In this case it depreciates which means that the rate is 1-0.18 = 0.82.
we know it will be worth 15,000,
So substituting would give us

1/2 = 0.82^t
log (1/2) = t log(0.82)
t =
Therefore, t is roughly 3.5 years.
Great question, hope this helps.
