<PRE><B>Question 564033</B>
If the value of land in an area is increasing 5 percent a year, how long will it take for property values to double? 
-----------------------
Let x be the original property value.
If it is doubled the value will be 2x:
---
Equation:
2x = x(1.05)^t
---
2 = (1.05)^t
------
t = log(2)/log(1.05)
---
t = 14.2 years
