Answer:
87.72%
Explanation:
The effective capacity of the Academic Computing Center (ACC) is 90% of 1,900 students = 90% x 1,900 = 1,710 students.
If the actual number of students that got orientation sessions is 1,500 then the efficiency of the ACC is = (1,500 / 1,710) x 100 = 0.8772 x 100 = 87.72%
