Answer:
625
Explanation:
Let's take 1998, our closest year. We know that 2009 is 11 years away from 1998, meaning we will multiply 35 by 11, and then add it to the student count from 1998.
35 * 11 = 385
Then we take the two numbers and add them together:
240 + 385 = 625
If the pattern continues, there will be 625 students.
