Compare, order, and estimate whole numbers and decimals using place value and magnitude sense.

Defend the most reasonable estimate

Problem

A library has \(2,487~\text{books}\) on one floor and \(3,612~\text{books}\) on another. Round each floor count to the nearest hundred and use the rounded sum to determine the most reasonable proposed total from \(5,000,~6,000,~7,000,~\text{and}~8,000~\text{books}\). State the proposed total and the rounded sum.

5,000; 2,000 + 3,000 = 5,000

7,000; 3,000 + 4,000 = 7,000

6,000; 2,500 + 3,600 = 6,100

8,000; 4,000 + 4,000 = 8,000
