Verified Answer
Looking at the graph, we can see that there are 300 students who work at least 20 hours per week (200 between 20-29 hours and 100 at 30+ hours), out of a total of 400 students.
So the percentage of students who work at least 20 hours per week is:
(300/400) x 100% = 75%
Therefore, the answer is C.
