What is the difference between the total number of students from state A in 2004 and 2005 combined and the total number of students from state B in 2008 and 2009 combined?

Accepted Answer

**Solution:**

1. Calculate the total number of students from state A in 2004 and 2005:
   - In 2004: 260 students
   - In 2005: 320 students
   - Total for state A (2004 + 2005) = 260 + 320 = 580

2. Calculate the total number of students from state B in 2008 and 2009:
   - In 2008: 440 students
   - In 2009: 760 students
   - Total for state B (2008 + 2009) = 440 + 760 = 1200

3. Find the difference between these totals:
   $$	ext{Difference} = 1200 - 580 = 620$$

**Answer:** 620
