This problem is about solving compound inequalities—treating the double inequality as two constraints that $L$ must satisfy simultaneously. The key insight is to isolate $L$ by performing the same operations on all three parts: add 2, then divide by 2.5. Once you have the range, you'll identify which whole numbers fall within it.
