Question

For a music concert, organizeris stated that 850 people attended the final attendance was actually 922. Which of the following represents the appromixate percent error of the orginalg attendance

Answer 1

To calculate the approximate percent error of the original attendance, you can use the following formula:

\[
\text{Percent Error} = \left( \frac{\text{Actual Value} - \text{Estimated Value}}{\text{Actual Value}} \right) \times 100
\]

In this case:

- Actual Value = 922 (the final attendance)
- Estimated Value = 850 (the original estimate)

Substituting the values into the formula:

\[
\text{Percent Error} = \left( \frac{922 - 850}{922} \right) \times 100
\]
\[
= \left( \frac{72}{922} \right) \times 100
\]
\[
\approx 7.80\%
\]

Therefore, the approximate percent error of the original attendance is about **7.80%**.
