Difficulty: Easy
Correct Answer: 96
Explanation:
Introduction / Context:
A division near 18 and a product near 4.5*8 provide easy mental approximations. Subtract the second from the first and select the nearest choice. Options differ by only a few units, so keep approximations tight.
Given Data / Assumptions:
Concept / Approach:
Approximate Term1 with 2376/18 ≈ 132. Then compute Term2 around 4.5*8 = 36, with a small upward correction. Subtract to obtain the final estimate and compare to options.
Step-by-Step Solution:
Verification / Alternative check:
Use 2375.85/18.01 ≈ 131.99 and 4.525*8.05 ≈ 36.50; difference ≈ 95.49; nearest to 96.
Why Other Options Are Wrong:
103 is too high; 88 and 90 are low versus the computed mid-90s result.
Common Pitfalls:
Dividing by 18.01 as if 18.1 (which would understate Term1 more) or rounding the product too coarsely to 36 without the 0.4–0.5 bump.
Final Answer:
96
