Without being able to see the image, I can’t provide an exact amount based on the graph. However, if the line on the graph represents Amanda's earnings based on hours worked, you can typically find the amount she makes for eight hours by locating the point corresponding to eight hours on the x-axis and seeing where that point intersects the line, then following that vertical line to the y-axis to find the dollar amount.
Since I can't see the graph, I would recommend checking the value on the y-axis at the point where x=8 hours to make your prediction. If you provide me with the values plotted on the line around that point, I can help you interpret it!
