Answer:
- After 8 years
Step-by-step explanation:
Given:
- Initial price $56000
- Target price $20000
- Rate of depreciation 12% or 0.12
The equation for this:
- P(t) = 56000*(1 - 0.12)^t
Find the value of t:
- 20000 = 56000*0.88^t
- 0.88^t = 20000/56000
- 0.88^t = 0.35714285714
- t = log 0.35714285714 / log 0.88
- t ≈ 8
SOLUTION
.
- P(n) = 56.000 × (1 - 0,12)ⁿ
.

.
20.000 = 56.000 × (1 - 0,12)ⁿ
20.000 = 56.000 × 0,88ⁿ
0,88ⁿ = 20.000/56.000
