Answer
Answer:
$1.50 per book
Explanation:
Step1: Identify two points from the table.
Let $(x_1, f(x_1)) = (100, 50.00)$ and $(x_2, f(x_2)) = (250, 275.00)$.
Step2: Calculate the change in profit ($\Delta f(x)$).
$$ \Delta f(x) = f(x_2) - f(x_1) = $275.00 - $50.00 = $225.00 $$
Step3: Calculate the change in books sold ($\Delta x$).
$$ \Delta x = x_2 - x_1 = 250 - 100 = 150 $$
Step4: Calculate the rate of change (slope).
$$ \text{Rate of Change} = \frac{\Delta f(x)}{\Delta x} = \frac{$225.00}{150} = $1.50 \text{ per book} $$
