To predict how much Amanda will make for watching her little cousins for seven hours, we would need to refer to the graph you mentioned. Since I can't see the graph, I cannot directly analyze it.
However, if you have additional information or a description of the graph (like how much she earns per hour), I can help you calculate her earnings for seven hours based on that information.
If you have confirmed answers like $70, $75, $105, or $110, you might want to choose the figure based on the hourly rate shown in the graph. If you can provide that, I'd be glad to assist!
