A coordinate plane's x-axis ranges from 0 to 300 by 50-unit increments and the y-axis ranges from 0 to 12,000 by 2,000-unit increments. The x-axis is labeled 'Number of Laptops Sold' and the y-axis is labeled 'Revenue' with dollar units.

SmartComputer makes and sells laptops. The graph here shows the revenue of SmartComputer as a function of the number of laptops sold. Interpret the graph. How much revenue is earned if 75 laptops are sold?

To interpret the graph, we need to identify the point that corresponds to selling 75 laptops on the x-axis and determine the corresponding revenue value on the y-axis.

Since the x-axis represents the number of laptops sold and ranges from 0 to 300 in increments of 50, the point for 75 laptops falls between 50 and 100.

Looking at the y-axis, which represents revenue in increments of $2,000 ranging from $0 to $12,000, we can determine the revenue corresponding to 75 laptops sold.

If the graph shows a linear relationship, we can estimate that:

  • At 50 laptops, the revenue might be around $4,000 (hypothetical approximation),
  • At 100 laptops, the revenue might rise to around $8,000 (hypothetical approximation).

Since 75 laptops is halfway between 50 and 100, we would estimate the revenue at that point to be around the midpoint of $4,000 and $8,000, which is $6,000.

Therefore, the answer is $6,000.
