Right Answer: 1500
We know that 675 of the students surveyed said they cheated in 1 to 7 courses, and this represents 45% of the total students that participated in the survey, as shown in the graph.
If we want to know the total students surveyed (100%) we can use the Rule of Three as follows:
if 45% represents -----675 students
100% represents--------X students
or
45% -----675 students
100% --------X students
And this is solved in the following way:

Finally:
X=1500>>>>>This is the total amount of students surveyed or the 100%
