Question

the population of a community was 68000 at the beginning of 2000

Answer 1

SOLUTION

To solve the question, we will use the growth formula

$\begin{gathered} P(t)=P_o(1+r)^t \\ where\text{ } \\ P(t)\text{ = population after time t which is 25 years = ?} \\ P_o=initial\text{ population = 68,000} \\ r=growth\text{ rate = 1.9}\%=\frac{1.9}{100}=0.019 \\ t=2025-2000=25\text{ years } \end{gathered}$

Applying, we have

$\begin{gathered} P(t)=68,000(1+0.019)^{25} \\ =68,000(1.019)^{25} \\ =68,000\times1.600864 \\ =108,858.79255 \end{gathered}$

Hence the answer is 108,859

Hence the answer is option A
