Difficulty: Easy
Correct Answer: 355
Explanation:
Introduction / Context:
We approximate a percentage of a fixed number and add a product of two decimals. The problem belongs to an approximation set, so we round to the nearest offered integer.
Given Data / Assumptions:
Concept / Approach:
Compute each component with two-decimal accuracy and sum. The closest integer option among the choices is selected.
Step-by-Step Solution:
Verification / Alternative check:
If we rounded 5.01 to 5.0, we would get 32.91 * 5 = 164.55 and a total ≈ 355.80, still pointing to 355–356. With available choices, 355 is best.
Why Other Options Are Wrong:
Common Pitfalls:
Multiplying 32.91 by 5.01 incorrectly (e.g., adding 5.01 and 32.91) or mishandling the small 0.01 adjustment. Break the product into two parts for clarity.
