<PRE><B>Question 357168</B>
A piece of machinery valued at $250,000 depreciates at a fixed rate of 12% per year. After how many years will the value have depreciated to $100,000?
------------------------------
Each year the item retains 88% of its last-year value.
---
Solve: 250,000(0.88)^x = 100,000
0.88^x = 0.4
---
x = [log0.4]/[log0.88]
---
x = 7.168 years
