Question

The population of Mathlandia in 1995 was 23,473 and was projected to grow at a rate of 12% per decade. Predict the population in the year 2010.

27,822
29,445
39,435
976

Answer 1

`27,822`

Explanation:

Let

t-----> the time in decade

P----. the population

we know that

`P=23.473(1+0.12)^(t)`

we have

`t=(2010-1995)/10=15/10=1.5\ decade`

substitute

`P=23.473(1.12)^(1.5)=27,822`
