The population of an area starts at 100,000 people.  It increases by 60% over 10 years due to birth.  In that same time, 2000 people leave per year from emigration and 2500 people come in per year from immigration.  How many people are in the area at the end of 10 years?

The population increased by 100000*.6=<<100000*.6=60000>>60,000 from births
They lost 2000*10=<<2000*10=20000>>20,000 people from emigration
They gained 2500*10=<<2500*10=25000>>25,000 people from immigration
That means the net increase from people moving was 25000-20000=<<25000-20000=5000>>5,000
So the total population is 100,000+60,000+5,000=<<100000+60000+5000=165000>>165,000
#### 165,000
