Quizplus · Accepted Answer

The chart shows that there are 8 officers who each supervise 15 employees, and 3 officers who each supervise 14 employees. 
Therefore, the total number of employees supervised by the surveyed officers is: 
8 officers x 15 employees each = 120 employees 
3 officers x 14 employees each = 42 employees 
Total = 120 + 42 = 162 employees 
Therefore, the closest answer choice is C) 127.
