To find out how many freshmen will be assigned to each orientation session, we need to divide the total number of freshmen by the number of orientation sessions.
Given:
- Total freshmen = 3,525
- Total orientation sessions = 15
We perform the division:
\[ \text{Number of freshmen per session} = \frac{3525}{15} \]
Calculating this gives:
\[ \frac{3525}{15} = 235 \]
Thus, each orientation session will include 235 freshmen.
