Answer:
1470 students do not have a full-time or part-time job
Step-by-step explanation:
We have a relationship between students who have a part-time job and those who do not. The ratio is 7 out of 10 students.
Then we use this relationship as a conversion factor.
If of 10 students, 7 of them have a job, then of 4900 students, how many of them have a job?
[tex]4900 * \frac{7}{10}=3430[/tex] students
Finally, those who do not have a job are:
[tex]4900- 3430 = 1470[/tex]
