Question

The population of a town increased from 3700 in 2005 to 5250 in 2010. Find the absolute and relative (percent) increase.

Answer 1

5250-3700= 1550 = absolute increase

1550/3700=155/370= 31/74 =about .4189= 41.89% per 5 years= relative increase over 5 years

5250= 3700e^5r

5r=ln(74/31)

r = .2ln2.3871

r= about .174= 17.4% annual percentage growth
