To determine the correct graph that represents how many boxes of cookies the scout has over time, we need to analyze the situation:
- The scout starts with 100 boxes of cookies.
- They sell 25 boxes every 3 hours.
This means that for every 3 hours, the number of boxes sold will decrease by 25. We can calculate how many boxes remain over time:
- After 0 hours: \(100\) boxes (start)
- After 3 hours: \(100 - 25 = 75\) boxes
- After 6 hours: \(75 - 25 = 50\) boxes
- After 9 hours: \(50 - 25 = 25\) boxes
Now, looking for the graph that reflects the above points:
- At \(0\) hours, there are \(100\) boxes.
- At \(3\) hours, there are \(75\) boxes.
- At \(6\) hours, there are \(50\) boxes.
- At \(9\) hours, there are \(25\) boxes.
The only graph that accurately depicts the points \((0, 100)\), \((3, 75)\), \((6, 50)\), and \((9, 25)\) is:
The second graph:
- It shows the points as \((0, 100)\), \((3, 75)\), \((6, 50)\), and \((9, 25)\), accurately depicting the decrease in boxes over time.
Thus, the correct choice is the second graph.
