Percentage mix approximation: 134% of 3894 + 38.94% of 134 ≈ ?

Introduction / Context:
We combine two percentage computations. The first is a large percentage of a large number; the second is a moderate percentage of a small number. Summation followed by rounding to the closest MCQ option is the goal.

Given Data / Assumptions:

• Compute: 1.34 * 3894 + 0.3894 * 134.
• Standard rounding to the nearest listed value is acceptable.

Concept / Approach:
Convert percentages to multipliers and compute both terms accurately enough to pick the closest integer result from the options.

Step-by-Step Solution:

Verification / Alternative check:
Even slight rounding on either component leaves the total close to 5270, not near 5000 or 5500 options.

Why Other Options Are Wrong:

• 5000 and 5500: Too far from 5270 based on direct computation.
• 5300: Slightly high but still farther than 5270 from the true value.

Common Pitfalls:
Misplacing the decimal in percentages (e.g., using 134% as 0.134) or rounding too early. Keep two decimals until the end for a stable approximation.

Final Answer:
