bar graph
The x-axis is labeled Time (minutes) and goes from 0 to 120 in increments of 20. The y-axis is labeled Frequency and goes from 2 to 12 in increments of 2. The 0-20 minutes bar goes to 5. The 21-40 minutes bar goes to 8. The 41-60 bar goes to 6. The 61-80 minutes bar goes to 10. The 81-100 bar goes to 2. The 101-120 bar goes to 9.

Key: 3 | 5 means 35
Correct answer A. 8
Incorrect answer B. 5
Incorrect answer C. 7
Incorrect answer D. 9
A. 8 students collected more than 43 cans, as we can see from the given stem-and-leaf plot that there are 3 students with a stem of 4 and a leaf value greater than 3 (i.e., 4, 4, 5), and there are 5 students with a stem of 5 (i.e., 0, 3, 3, 6, 8), which gives us a total of 8 students.
To answer the question, we need to determine the height of the bar corresponding to the 81-100 minutes range on the y-axis of the bar graph. Looking at the given information, we can see that the bar for the 81-100 minutes range goes up to 2 on the y-axis.
Therefore, the number of students who spend 81 to 100 minutes on chores is 2.
The correct answer is C. 2.
