1. The problem asks which graph best represents the total amount of recycling collected at Dean's school over the course of the year. 2. Important to note: At the beginning of the year, very few recyclables were collected, but recycling increased quickly as students learned more about the program. 3. This means the graph should start low on the y-axis (total recycling collected) and increase over time (x-axis: weeks). 4. Let's analyze each graph description: - Graph 1: Starts high and decreases steadily — this contradicts the problem since recycling started low. - Graph 2: Starts low, rises quickly, then levels off and slightly decreases — this shows initial growth but a decrease at the end, which is unlikely for total collected recycling (which should not decrease). - Graph 3: Starts high, decreases, rises slightly, then decreases again — contradicts the problem since it starts high. - Graph 4: Starts low and steadily increases over time — matches the problem description perfectly. 5. Therefore, the best graph to represent the total recycling collected over the year is Graph 4. Final answer: Graph 4 (bottom-right)
