Final answer:
To find out how many fewer points Ana's class earned on Monday compared to Thursday, one would subtract the points earned on Monday from those earned on Thursday using the graph's data. Because the actual data is not provided in the question, we can't calculate the exact difference, but we can explain the process.
Step-by-step explanation:
The student has asked about the difference in points earned by Ana's class on two different days of the week, specifically Monday versus Thursday. To answer this, one would typically look at a graphical representation of the data, like a bar graph or line graph, showing the points earned on each day of the week. This is a mathematical exercise in interpretation of data from a graph. However, since the actual graph data for Ana's class is not provided here, we must respond by explaining the process the student would take to determine the answer, rather than giving the specific number of points earned.
The process involves identifying the value representing the number of points earned on Monday and the value for Thursday on the graph. Once these values are obtained, the student would subtract the Monday value from the Thursday value. For instance, if the graph showed 30 points for Monday and 50 points for Thursday, the class earned 20 fewer points on Monday than on Thursday (50-30=20).
