Question

Chapter 1, Problem 10QC

To determine

To Evaluate: Estimate of 524−349

Expert Solution & Answer

Answer to Problem 10QC

170

Explanation of Solution

Given information:

524−349

Concept Used:

Estimate of any value numerical value can be found by rounding it to its nearest ten

For example: estimate of 12 would be 10 and that of 18 would be 20.

Calculation:

We can write-

524−349≈ 520−350 (Round 524 and 349 to nearest 10)

Hence,

520−350_ 170_

Therefore,

524−349 ≈ 170
