Question

1. melissa estimated that she would read 250 pages last week. she read 290 pages. what is the percent error of melissa’s estimate? round to the nearest whole percent.

Explanation:

Step1: Find the absolute error

The absolute error is the absolute value of the difference between the actual value and the estimated value. So, \( |290 - 250| = 40 \).

Step2: Use the percent error formula

The formula for percent error is \( \text{Percent Error} = \frac{|\text{Actual} - \text{Estimated}|}{\text{Estimated}} \times 100\% \). Substituting the values, we get \( \frac{40}{250} \times 100\% \).

Step3: Calculate the value

First, \( \frac{40}{250}=0.16 \). Then, \( 0.16\times 100\% = 16\% \).

Answer:

16%
