To determine the revenue earned when 75 laptops are sold, we need to analyze the graph and see where 75 intersects the 'Number of Laptops Sold' axis (x-axis) and the corresponding value on the 'Revenue' axis (y-axis).
Given the y-axis ranges from 0 to 12,000 with increments of 2,000, the revenue points might be labeled at 0, 2,000, 4,000, 6,000, 8,000, 10,000, and 12,000.
Assuming you have a graph showing the revenue line based on the number of laptops sold, we check the point that corresponds to 75 laptops sold. Typically, a linear graph indicating revenue will have a slope reflecting the revenue per unit sold.
If the graph indicates that at 75 laptops sold the revenue is at 6,000 on the y-axis, then the correct response would be $6,000.
Choose this response based on what you see in the graph. If the graph suggests otherwise, please verify the point of intersection for 75 laptops to determine the revenue accurately. However, given the options and standard increments, $6,000 seems to be the likely correct answer.
