Problem statement
Write a function apply_discount(total) that applies a discount based on the total amount (a non-negative number):
- If total >= 500: apply a 20% discount.
- Else if total >= 200: apply a 10% discount.
- Else if total >= 100: apply a 5% discount.
- Otherwise: no discount.
Return the final amount rounded to 2 decimal places (use round(amount, 2)).
Task
Use conditional branching to select the correct discount tier and compute the discounted total.
