Question

nick estimates his piggy bank has $89 in it, but when he opens it he actually has $66. what is the percent error in nicks estimate? ?% round to the nearest whole

Explanation:

Step1: Find the absolute error

The absolute error is the absolute value of the difference between the estimated value and the actual value. So, \( |89 - 66| = 23 \).

Step2: Use the percent error formula

The formula for percent error is \( \text{Percent Error} = \frac{|\text{Estimated} - \text{Actual}|}{\text{Actual}} \times 100\% \). Substituting the values, we get \( \frac{23}{66} \times 100\% \).

Step3: Calculate the value

\( \frac{23}{66} \times 100\% \approx 34.85\% \), and rounding to the nearest whole percent gives \( 35\% \).

Answer:

35%
