Beyond the Answer

To estimate the country's population in 2026 using an exponential growth model, we can apply the formula: \[ P(t) = P_0 \times e^{(r \times t)} \] Where: - \(P(t)\) is the future population, - \(P_0\) is the initial population (159 million), - \(r\) is the growth rate (1.564% or 0.01564 as a decimal), - \(t\) is the time in years from the base year (2026 - 2011 = 15 years). Now, plugging in the values: \[ P(15) = 159 \times e^{(0.01564 \times 15)} \] Calculating the exponent: \[ 0.01564 \times 15 = 0.2346 \] Now, calculate \(e^{0.2346} \approx 1.2646\): \[ P(15) = 159 \times 1.2646 \approx 200.488 \] Thus, the estimated population in 2026 is about **200.49 million** (rounded to the nearest hundredth).
