Don't fart on the Isles
Problems 15, 16, and 17 all refer to the following:
In the very center of the Irenic Sea lie the beautiful Nisos Isles. In 1998 the number of people on these islands is only 200, but the population triples every 25 years. Queen Irene has decreed that there must be at least 1.5 square miles for every person living in the Isles. The total area of the Nisos Isles is 24,900 square miles.
Problem 16
Estimate the year in which the population of Nisos will be approximately 6,000.
Solution
Solution 1
We could triple the population every 
years and make a chart:
Year: 2000 Population: 200
Year: 2025 Population: 600
Year: 2050 Population: 1800
Year: 2075 Population: 5400
Year: 2100 Population: 16200
The closest year is 2075, or 
NI TAI GUO FENNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN LAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
We could find out how many periods of 25 years we need to triple by dividing our total from our present number.
The power of 
that 
is closest to is 
Therefore, after periods, we will be closest to 
.
