For a survey, students were assigned to either Ror group V. Combined, the students in both groups answered a total of 17 questions. Of these, a total of 9 questions were answered by the students in V. The equation 4r + 9 = 17 describes this dno18 situation, where r represents the number of %3D questions answered by each student in group R. Which of the following is the best interpretation of 4r in this context? A) The number of students in group B) The number of students in group V C) The total number of questions answered by students in group R D) The total number of questions answered by students in group V
