Jamaal purchased the same number of action figures daily for one week, and then he sold most of them on the Internet. We want to sketch a qualitative graph to represent the situation. Let's remember the definition of this type of graph.

Qualitative graphs are graphs used to represent situations that may not have numerical values or graphs in which numerical values are not included.

Notice that we do not know the initial number of the figures, or how many figures Jamaal purchased each day — the numerical values are not included. We only know how the total number of action figures changed over time.

At first, Jamaal purchased the same number of action figures daily for one week. This means that the total number was growing daily by the same amount.
Then he sold most of them on the Internet. As a result, the total number of figures decreased by a significant amount.

We can model this situation using a qualitative graph that very closely resembles a bar graph. There will not be any numbers on either of the axes because we are not given any numerical values.

Note that this is just one of many ways to represent the situation.
