To determine how many desks would be used to depict the enrollment of 2,100 students in a picograph, we need to understand how many students each desk represents.
From the information provided, it appears that the highest enrollment is 1,800 (from the side of the graph), and it corresponds to 6 desks if we consider 300 students per desk (based on the 300 students indicated at the top of the graph).
Here's the breakdown:
- Each desk represents 300 students.
- For 2,100 students, we can calculate the number of desks needed:
\[ \frac{2100 \text{ students}}{300 \text{ students per desk}} = 7 \text{ desks} \]
Thus, a fifth high school with 2,100 students would be represented by 7 desks in the picograph.
The answer is 7.
