Answer 3

To evaluate the given expression, let's break it down step by step:

1. Start with multiplication and division from left to right: 100 - 30 ÷ 3 × 45 ÷ 25 + 3.5 + 4

2. Perform the division first: 100 - 10 × 45 ÷ 25 + 3.5 + 4

3. Next, perform the multiplication: 100 - 450 ÷ 25 + 3.5 + 4

4. Proceed with the division: 100 - 18 + 3.5 + 4

5. Add and subtract from left to right: 82 + 3.5 + 4

6. Finally, perform the addition: 82 + 3.5 + 4 = 89.5

Therefore, the result of the given expression is 89.5.
