The population of a town increases at a rate proportional to the population at that time. If the population increases from forty thousand to eighty thousand in 20 years, then the population in another 40 years will be
- A \(240000\)
- B \(160000\)
- C \(320000\)
- D \(640000\)
Answer & Solution
Correct Answer
(C) \(320000\)
Step-by-step Solution
Detailed explanation
\(P(t) = P_0 \cdot 2^{t/20}\) \(P(60) = 40000 \cdot 2^{60/20}\)
