Question

The population of a town at percent is $80000$. If the annual rate of increase is $4$, find the population after $4$ years. (use the formula:$A=p{(1+\frac{r}{100})}^n$, where $p$ is the original population)

Answer 1

P=original population$=80000$

Rate of increase $r=4$

$n=4$ years

$A=P{(1+\frac{r}{100})}^n$

$=80000\times {(1+\frac{4}{100})}^4$

$=93588.685$

$\approx 93599$
