Problem

A solution to a logistic model is given by S(t)=1001+9e−0.3tS(t)=\dfrac{100}{1+9e^{-0.3t}}. What is lim⁡t→∞S(t)\displaystyle \lim_{t\to\infty} S(t)? a) 1010 b) 1009\dfrac{100}{9} c) 100100 d) 00
Intuitive explanation

The logistic model describes growth that starts slow, accelerates, then plateaus at a maximum capacity—called the carrying capacity. As t→∞t \to \infty, the exponential term e−0.3te^{-0.3t} shrinks to zero because you're raising a number less than 1 to an increasingly large power. Once that term vanishes, you're left with just the numerator divided by 1, which reveals the long-term equilibrium the population approaches.
