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? 328 + 559 round the two numbers to the nearest ten. an estimate of the sum is 890. the actual sum is 887. how reasonable is your estimate when compared to the actual answer? a. reasonable. the estimate seems a little lower compared to the actual answer b. not reasonable. the estimate seems too low compared to the actual answer. c. not reasonable. the estimate seems too high compared to the actual answer. d. reasonable. the estimate seems a little higher compared to the actual answer

Explanation:

Step1: Compare estimate and actual

Estimate sum: \( 890 \), Actual sum: \( 887 \).

Step2: Analyze difference

\( 890 - 887 = 3 \). The estimate is slightly higher than actual. Check options: D says "Reasonable. The estimate seems a little higher...", which matches.

Answer:

D. Reasonable. The estimate seems a little higher compared to the actual answer.
