Answer:2 hours
Step-by-step explanation:
3x12,000=36,000
2x3=6divided by 3=2
We know that
38% of the incoming students own both a smartphone and a tablet
84% of the students own a smartphone
We are asked to find the percentage of students who own a smartphone
Let N be the total number of incoming students and S be the total number of students
So,
(N (38%) + S (84%)) / (N + S)
If we know the total number of students or incoming students, we can solve for the percentage by substituting the value of N or S
