Final answer:
To find the monthly commission for total monthly sales of $0.8 million, we use the line of best fit on the scatterplot. The closest commission amount is around $4500.
Step-by-step explanation:
To determine the monthly commission that the salesperson could expect to make when the total monthly sales are $0.8 million, we need to use the line of best fit for the scatterplot. The line of best fit represents the relationship between the total monthly sales and the commission earned. We can find the closest commission amount by finding the y-coordinate on the line of best fit for the given x-coordinate (total monthly sales = $0.8 million).
Based on the options given, we need to find the commission closest to the y-coordinate when x = 0.8. Using the line of best fit, we can estimate that the commission would be around $4500. Therefore, the correct answer is option C.
