Question
Obtain an estimate for the following computation by rounding the numbers so that the resulting arithmetic can easily be performed by hand or in your head. Then, use a calculator to perform the computation. How reasonable is your estimate when compared to the actual answer? \( 32.46-14.189 \) An estimate of the difference is 18 . (Type a whole number.) The actual difference is 18.271 . How reasonable is your estimate when compared to the actual answer? A. Reasonable. The estimate seems a little higher compared to the actual answer. B. Reasonable. The estimate seems a little lower compared to the actual answer. C. Not reasonable. The estimate seems a little lower compared to the actual answer. D. Not reasonable. The estimate seems a little higher compared to the actual answer. D. A.

Answer
The estimate of 18 is a little lower than the actual difference of 18.271, so the estimate is not reasonable.

When rounding for estimation, we rounded 32.46 to 32 and 14.189 to 14. Thus, the estimated difference is \(32 - 14 = 18\). This gives us a quick way to gauge the expected outcome without getting into more complex calculations. The actual computation, \(32.46 - 14.189\), gives us an exact difference of 18.271. Your estimate is fairly close to the actual calculation but slightly below it. This indicates that while the estimate is useful for a rough idea, it can occasionally miss precise values, leading to the option that best fits this scenario.
