Question

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

Answer 1

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}\%=(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*1.600864 \\ =108,858.79255 \end{gathered}`

Hence the answer is 108,859

Hence the answer is option A
