Question

You thought you had finished 35 pages, but you actually read 32 Pages. What was your percent error?

Answer 1

`(35-32)/(32) * 100=(75)/(8)=9.375\%`

Answer 2

9.375%

Explanation:

Percentage Error formula

`\textsf{Percentage error}=\sf \left|(estimated\:value\:-actual\:value)/(actual\:value) \right| * 100\%`

Given:

• Estimated value = 35 pages
• Actual value = 32 pages

Substitute the given values into the formula:

`\begin{aligned}\implies \textsf{Percentage error}&= \left|(35-32)/(32) \right| * 100\%\\\\&=\left|(3)/(32) \right| * 100\%\\\\&=0.09375 * 100\%\\\\&=9.375\%\end{aligned}`

Therefore, the percentage error was 9.375%.
