New Library

library

The little town of Radiusville has only one public library.  Many of the citizens feel that recent growth in the town’s population warrants the construction of an additional library.  The current population of the town is 15000 people.  According to the town’s bylaws, construction of a new library will begin when the population reaches 26000 people.  If the annual growth rate of the town has been consistently 4.5% and the year is 2005, in what year will the town need to build a new library?
