Answer

Explanation:

Step1: Recall average rate - of - change formula

The average rate of change of a function $y = f(x)$ over the interval $[x_1,x_2]$ is $\frac{f(x_2)-f(x_1)}{x_2 - x_1}$. Here, $x$ is the number of months and $y$ is the value of the stock portfolio. The initial month $x_1 = 0$ and the final month $x_2=8$. The value at $x = 0$ is $y_1=52840$ and the value at $x = 8$ is $y_2 = 545903$.

Step2: Calculate the average rate of change

The average rate of change $=\frac{y_2 - y_1}{x_2 - x_1}=\frac{545903 - 52840}{8-0}=\frac{493063}{8}=61632.875\approx61633$.
